1. When buying a rear view mirror, look at its appearance and work. An excellent smart rear view mirror navigation integrated machine has a good appearance, exquisite workmanship, and the advantages and disadvantages are clear at a glance. If the materials and workmanship are not good, quality problems are prone to occur in the hot summer weather.
2. The purchase of rear-view mirrors depends on its price and reputation. We should shop around to see the price of smart rear-view mirrors. We should not just look at the price of smart rear view mirrors. The so-called bargains are not good ones.
1、What’s we can provide?
1) We can provide high quality OEM/ODM for any auto lights and auto mirrors. For OEM, we supplied truck mirrors to US OE factory and provided truck lights to Peru OE manufacturer. We can make 100% same products as samples. For ODM, just inform us your opinion or request, we will design and send different drawings to you. After you confirm, we can make it out.The high brightness of large truck lights is relatively speaking, and the attributes of trucks determine the quality of their light sets. Family cars rarely run at night, but trucks often run 24 hours a day, and even some vehicles are stopped. Therefore, the brightness of the truck light group must be high enough, and the driver's vision is wider and brighter, which can effectively reduce the accident rate. There are several reasons why truck lights look dazzling: First of all, the truck uses 24V power supply and two batteries in series, so it can support more powerful light bulbs. Especially the halogen lamp, the power is more than twice as high as that of a family car. The power of halogen bulbs for family cars is about 50W, while the power of halogen bulbs for trucks can exceed 100W.
Another reason is the height of the lights installed on trucks. Truck lights are generally higher, and the driver’s field of vision is wider. The height of truck lights is generally much higher than that of cars/passenger cars. The lights of trucks are exactly parallel to the eyes of the car driver.
The advantage of this height difference is still great. Is the flashlight high in brightness? But when someone puts a flashlight directly at your eyes, you will feel that the flashlight is extremely bright! When changing the illumination angle of the flashlight to not directly illuminate the eyes, you will find that its brightness is not high! The height of the truck lights is almost the same as the height of the eyes of the car driver, so when the truck lights are on, the car driver will feel dazzling or even temporarily blind. What's more, the power of truck bulbs is generally higher than that of car bulbs. Therefore, when driving at night, the brightness of truck lights will be high, even dazzling!
LED is the abbreviation of Light Emitting Diode, that is, light-emitting diode.
LED was invented in the 1960s. The principle is that when a forward voltage is applied to a light-emitting diode, free electrons and holes meet and appear in the form of light emission. Early LED lights were red, and now through the ratio of different elements, LED lights can emit any color people want, which is widely used in vehicle lighting, interior atmosphere, etc.
At present, more and more trucks in our country use LED as the light source of car lights, but they are only used in daytime running lights. When the LED is working, only about 25% of the electricity is converted into light energy, and the remaining electricity is converted into heat and dissipated. LEDs are particularly sensitive to temperature, and thermal energy affects the performance of LEDs. If the heat cannot be dissipated in time, the light will attenuate first and the brightness will decrease.
Advantage
High brightness, the highest brightness under the same power.
Long life (more than 30,000 hours).
High reliability, no fear of vibration.
The lighting speed is fast.
It is small in size and can realize many other functions.
Disadvantage
The cost is relatively high.
The LED itself has a large amount of heat and needs to be used with a heat sink.
LED with poor heat dissipation will have severe light decay and affect brightness.
The top of the lights on top of a truck called the marker light. The marker lights are the lights on the front and rear sides of the car. There are also marker lights on the roof and sides of large trucks. Marker lights, light literally, "show" means warning; "outline" has the meaning of outline, so the marker lights are a kind of warning lights, used to remind other vehicles to pay attention to the lights. It is installed at the edge of the top of the car, which can express both the height and width of the car. Safety standards stipulate that position lights must be installed in cars with a height of more than three meters. The color of the position lights is white in front and red in the back.
The evolution of automobile headlights has experienced more than a century of technological precipitation, starting from the first kerosene lamp, to the halogen bulb of the electrical age, to the xenon headlight, to the LED light source, and then to the latest laser headlight.
Car lights can be divided into illuminating lights and signal lights according to their functions. Lighting lights include headlights, fog lights, brake lights, etc.; Signal lights include turn signal lights, hazard warning lights, tail lights, etc.

The reason why light trucks try not to replace the headlight assembly is mainly because the replacement of the headlight assembly is a car light modification, and the annual inspection has strict requirements for the headlight modification, and unauthorized modification is not allowed, otherwise it will cause the annual inspection of the car to fail. Pass, but there are actually ways to pass the annual inspection.
Under normal circumstances, as long as the replaced headlight assembly is the original one, it can pass the annual inspection as the original one. If you are told that the light does not meet the brightness requirements during the annual inspection, you can still pass the annual inspection as long as it is properly adjusted. In addition, the replacement of the headlight assembly involves a certain risk, so it is recommended to go to a regular service station for modification.
Is it tricky to change the car lights at the roadside simple repair shop?
Under normal circumstances, the simple maintenance shop on the roadside does not say 100% replacement of car lights, at least 60% is tricky. Many car owners are cheap and use the lights of the subsidiary factory as the lights of the main factory, because the vehicles produced by the subsidiary factory The cost of accessories is relatively low. Compared with the accessories produced by the main factory, the price of the accessories is very different. Therefore, the simple car repair shop on the roadside will use the accessories produced by the auxiliary factory to earn the difference.
Attachment: How to judge the original headlights and the auxiliary headlights
Compared with the original headlights, the quality of the sub-factory headlights is uneven, there are many defects in the corners, and the logos engraved on the headlights are also blurred. The sub-factory is also due to insufficient manufacturing level, so the gap between the lamp and the body installation is uneven, and the left-to-right deviation is large. In addition, the headlights of the sub-factory have poor illumination effects, long response times, and even different brightnesses between left and right.
Recently, a netizen broke the news on the website, saying that when a member of their fleet passed the Ningbo highway intersection, the traffic police stopped him and issued a serious fine: 12 points deducted from the driver’s license and a fine of 200 yuan. Why is this? The reason is simply that a set of LED lights is installed in the front of the car! Next, let's take a look at what is going on.
Why would I be punished so severely for just adding an LED light? What exactly is this for? Later, after understanding, it turned out that it was because the LED light was installed in an improper position, and the LED light was too strong, it would directly "blind" the electronic eye, and the traffic police would think it was blocking the number plate when it was checked.
For example, such a set of LED tubes are installed at the air inlet of the car head. I believe that many cars have installed this kind of lights, because the lights are really bright at night, and the driving safety at night will be improved a lot. The purpose is no problem. For safety, But it won't work if it is installed in the wrong position.
It is understood that the traffic police department believes that this LED light can emit bright light and is installed close to the license plate. Not only the human eye cannot recognize the license plate number at night, but it can also cause the electronic eye to overexpose and fail to recognize the vehicle number plate. The traffic police department said Some truck drivers illegally install such light sources in order to avoid the capture of the electronic eye on the "passenger and freight separation, speed limit" section.
Indeed, the brightness of this kind of strong LED lights at night can be described as "blind and blind". In fact, from another perspective, it is simply a kind of annoying rogue lights. If it is night, the car will meet the car. , It can almost be expected that the driver of the car will drive with his eyes closed, and the scene of 10,000 horses running on grass and mud in his heart. I hope everyone will pay attention to the use of LED lights.
The top of the lights on top of a truck called the marker light. The marker lights are the lights on the front and rear sides of the car. There are also marker lights on the roof and sides of large trucks. Marker lights, light literally, "show" means warning; "outline" has the meaning of outline, so the marker lights are a kind of warning lights, used to remind other vehicles to pay attention to the lights. It is installed at the edge of the top of the car, which can express both the height and width of the car. Safety standards stipulate that position lights must be installed in cars with a height of more than three meters. The color of the position lights is white in front and red in the back.
Headlights are a tool that is convenient for many drivers to illuminate when they are driving at night. Nowadays, there are more and more brands of car lights on the market. Many car owners don’t know how to choose when buying and don’t know what brand of car. The lights are better? How much do you know about the brand of car lights? Let's take a look with me below!

At present, automobile headlights mainly include halogen lamps, xenon headlights, and LED headlights. Laser headlights are rarely introduced here. These three types of headlights have their own characteristics. Which one you choose depends on your choice. demand.
The halogen lamp is equivalent to an upgraded version of the incandescent lamp. The light emitted by the halogen lamp is yellowish. The advantage is strong penetrability. It can still provide the driver with a better view in rain, snow and fog. However, due to the insufficient lighting brightness of the bulb, the darker light makes the driver unable to judge the road well.
Xenon headlights generally refer to xenon lamps equipped with lenses. The color of xenon lamps is white. Compared with halogen lamps, xenon lamps have higher brightness, lower power consumption, longer life, and more stable lighting effects. Most models use xenon headlights. Xenon lamps also have shortcomings, not as strong as halogen lamps.
LED lights use cold light sources to emit light, so in the energy conversion, the energy consumption is low, and the power consumption is also lower. In addition, LEDs also have the advantages of fast lighting, simple structure, and freer shape of the lamp group. The disadvantage is that the heat is large. Because the brightness of a single LED element is low, to achieve the brightness level of a xenon lamp, a group of LEDs is necessary, and the cost is high.
Usually when we drive, whether it is reversing, changing lanes, or turning, we need to use rear-view mirrors, you can imagine how important a rear-view mirror is. So, do you know how to adjust the rear view mirror correctly? Let's take a look at it together, and see if you usually adjust it correctly?
Left rear view mirror
Before adjusting the rear view mirror, the seat should be adjusted first. The left rear view mirror can be adjusted in four directions: up, down, left, and right. The first is to adjust left and right, adjust to the body 1/4 of the mirror; if you adjust up and down, adjust to the sky and the ground each occupies 1/2.
Right rear view mirror
The right rear view mirror can also be adjusted in four directions, up, down, left, and right. The left and right adjustment is the same as the left rear view mirror, adjusted to the 1/4 of the mirror. If you adjust it up and down, adjust so that the sky occupies 1/3 of the mirror and the ground occupies 2/3.
Central rear view mirror inside the car
If you adjust the central rear view mirror, adjust it so that you can see the four corners of the rear windshield.
For the central rear view mirror in the car, it is usually easy to be ignored by the driver. In fact, its role is no less than that of the left and right rear view mirrors. When you need to brake suddenly, you can observe the situation of the car behind through this rear view mirror, and it can also be used when there are children in the back of the car.
Rear view mirrors are like the eyes of the driver. Correct adjustment can help the driver better observe the road conditions, reduce blind spots in the field of vision, and reduce risks. Therefore, it is necessary to master the correct adjustment method of the rear view mirror.
1. When buying a rear view mirror, look at its appearance and work. An excellent smart rear view mirror navigation integrated machine has a good appearance, exquisite workmanship, and the advantages and disadvantages are clear at a glance. If the materials and workmanship are not good, quality problems are prone to occur in the hot summer weather.
2. The purchase of rear-view mirrors depends on its price and reputation. We should shop around to see the price of smart rear-view mirrors. We should not just look at the price of smart rear view mirrors. The so-called bargains are not good ones.
The rear view mirror plays an important role in the driving process of the semi-trailer, which is equivalent to the eyes of the semi-trailer. How to use your own eyes correctly is the most important safety issue. Below we introduce how to use the semi-trailer rear view mirror correctly:
There are certain rules for rear view mirror adjustment
Everyone has different driving habits, and they usually adjust their rear view mirrors based on their feelings. In fact, the adjustment of the rear-view mirror still has certain rules. The following issues need to be paid attention to during the adjustment: For the interior rear view mirror, adjust the left and right positions so that the left edge of the mirror is just cut to the right ear of the image in the mirror. This means that under normal driving conditions, you cannot see yourself in the rear view mirror of the car, while the upper and lower positions are to place the distant horizon in the center of the mirror. For the left-side rear view mirror, the upper and lower positions place the distant horizon in the center, and the left and right positions are adjusted to 1/4 of the mirror surface area of the vehicle body. For the right side mirror, because the driver's seat is located on the left side, it is not so easy for the driver to grasp the right side of the vehicle. In addition, sometimes the need for parking on the roadside is required for the right side mirror when adjusting the up and down positions. The ground area should be larger, accounting for about 2/3 of the mirror surface. The left and right positions can also be adjusted so that the body occupies 1/4 of the area.
Semi-trailer rear view mirrors have limited coverage
Many people think that in order to eliminate blind spots or blind spots, the left and right rear view mirrors should be adjusted outward or downward as far as possible. This may be counterproductive, because blind spots cannot be eliminated, and doing so may also relax your observation of blind spots. A normal driver can see a range of about 200° to the left and right in front of him when he only rolls his eyes without turning his head back. In fact, the left and right rear-view mirrors plus the interior rear-view mirrors can only provide an additional viewing range of about 60°, so the remaining 100° is the blind spot we often call.
The reflectivity is different during the day and night
The size of the reflectivity is related to the material of the reflective film on the inner surface of the mirror. The greater the reflectivity, the clearer the image reflected by the mirror. The reflective film of automobile rear view mirror generally uses materials such as silver and aluminum, and their minimum reflectivity is generally 80%. High reflectivity will have side effects in some occasions. For example, when driving at night under the illumination of the headlights of the car behind, the reflection from the rear view mirror of the car will make the driver have a dazzling feeling and affect the driving safety, so the rear view mirror of the car is generally Using a rhombus mirror, although the mirror surface is also flat, its cross-section is rhombus. It uses the surface reflectivity of the rhombus mirror to be different from the inside reflectance to achieve no dazzling. In the daytime, a silver or aluminum back reflective film with a reflectivity of 80% is used, and at night, a surface glass with a reflectivity of only about 4% is used. For this reason, the inner rear view mirror in the daytime position should be properly rotated at night to adapt it to driving requirements.
