Is It Illegal to Modify Car Headlights to Xenon?

[DeBrody]

Modifying car headlights to xenon is illegal. Here are the specific details: Regulations: According to Article 16, Paragraph 1 of the 'Road Traffic Safety Law of the People's Republic of China,' it is explicitly stated that no unit or individual may assemble motor vehicles or alter the registered structure, construction, or characteristics of motor vehicles without authorization. Therefore, retrofitting xenon headlights after purchase constitutes an unauthorized alteration of the motor vehicle's structure or construction, which is considered illegal. Article 97 of the 'Road Traffic Safety Law of the People's Republic of China' also stipulates: 'Illegally installed alarms or emblem lights shall be forcibly removed and confiscated by the traffic management department of the public security organ.' Requirements: The low beam must not be less than 1,050 lumens, and the high beam must not be less than 1,450 lumens. The light intensity of a moving vehicle must not be less than 15,000 CD and not exceed 120,000 CD. The color temperature must not exceed 6,000 K; otherwise, the annual inspection equipment cannot detect the light.

It depends on the specific situation! When I retrofitted xenon headlights myself, I specifically checked the regulations. National regulations stipulate that retrofitted headlights must not exceed 6000K color temperature and must be equipped with dedicated lenses, otherwise the scattered light would be illegal. After modification, you must register the change with the vehicle management office and update the photo on the driving license. The key is to pass the light pattern inspection during the annual vehicle inspection. If you install bulbs without lenses, traffic police will definitely catch you. Moreover, forcibly converting original halogen assemblies to xenon will absolutely fail the annual inspection. The safest option is to buy a car model that comes with factory-installed xenon headlights. If you want to save money, choose compliant LED replacement parts—nowadays you can install focused models with fans for just 500 yuan.

When I worked as a vehicle inspector at the annual inspection station last year, I saw too many cases. Whether xenon light modifications are legal depends on three factors: whether the original lens is retained, whether the color temperature exceeds standards, and whether it's registered. Among those who replaced halogen lights with xenon lights themselves, nine out of ten failed the inspection line. Those with glaring blue light exceeding 6000K, foggy light covers, or scattered light beams would all be stopped. Especially the traffic police on night duty are even stricter—they deduct 12 points immediately upon seeing xenon lights without lenses. It's advisable to check the product quality inspection report before modification, focusing on anti-glare markings and 3C certification. If you really want to modify, opt for a lens kit with a cut-off function—spending two thousand is better than being fined five thousand.

A seasoned driver tells it like it is: There's really no need to retrofit xenon headlights these days. Last time, my buddy spent 3,200 yuan modifying his Passat, only to be asked to remove the bulbs on the spot during the annual inspection. Traffic regulations clearly state that modified lighting must not affect oncoming vehicles, and those glaring white retrofits are the most likely to get fined. Nowadays, traffic police units are equipped with lumen meters, and exceeding standards will be treated as illegal modification. Plus, if you encounter a driver with a dashcam who reports you, you'll get a ticket in no time. I later switched to compliant LED bulbs with yellow-white light and focusing cups for just 400 yuan, and they've been trouble-free for three years. If you really want to improve brightness, keeping the lens clean is more effective.
