For some car owners who like to modify, modifying headlights is the most basic thing. However, due to the great restrictions on vehicle modification in China, many riders are often worried. Can the headlights modified by the new car really pass the annual review?
For the choice of automobile headlights
First of all, the mainstream headlights on the market are divided into halogen headlights, xenon headlights and led headlights. Not to mention BMW's patented laser headlights.
Many low-end models are equipped with halogen headlights, and their service life is only about 500 hours. Generally, after half a year of use, there will be insufficient light. For halogen headlights, once the light attenuation exceeds 20%, the lumen value will be lower than the national standard 1200lm, which is theoretically unusable.
As for xenon headlights, the service life of light source headlights is generally 2 years or 50 thousand kilometers, and the national use standard is that the light attenuation is less than 30% within 2500 hours. If no stabilizer is added to the modified product, the light attenuation will exceed 30% within 500 hours.
At present, as the mainstream configuration of vehicles, the service life of led headlights is 5000 hours. Moreover, the light attenuation of led headlights is only 5% after 3000 hours of use, and its service life and light intensity are deeply loved by the majority of car owners.
Vehicle lamp detection regulations
According to the first paragraph of Article 16 of the Road Traffic Safety Law of the People's Republic of China, no unit or individual may assemble a motor vehicle or change the registered structure, structure or characteristics of a motor vehicle without authorization. As for the annual inspection, if only the lens is modified, the light can completely pass the detection of the detection equipment.
Check the headlights twice. The first is the appearance inspection. At this point, the inspector visually checks whether there are unauthorized modifications. Secondly, the instrument detection on the car is aimed at the detection of headlight brightness, divergence angle and consistency. Generally, as long as the brightness on both sides is the same, you can pass.
If there is a strong demand to modify the headlights, please note:
1. Control the color temperature of the modified headlight below 6000k and keep it around 4300k K. If the color temperature is too high or too low, it will not pass the headlight detector.
2. Assemble the lens system, calibrate the light irradiation angle offset, and pass the annual inspection without affecting the opposite traffic safety.
3. Try not to install the color difference lamp. The modification of this headlight will change the appearance and quality of the original headlight, which is likely to fail the annual inspection.
Here, if the owner wants to modify the headlights, try to use the original headlights for configuration upgrade, or choose a professional headlight modification shop for modification. It is not recommended to buy parts from third-party sub-factories without quality assurance for private modification, which may fail the annual inspection and cause danger to driving safety.
