Is modifying tail lights considered illegal modification?

[Arthur]

Modifying car tail lights is considered illegal modification. The regulations and precautions for car modifications are as follows: Regulations for car modifications: Cases where change registration will not be processed: Altering the brand, model, and engine model of the vehicle, except for engines that are optionally installed with the permission of the State Council's motor vehicle product authority; modifying the registered appearance and technical data of the vehicle, unless otherwise stipulated by laws, regulations, and national mandatory standards. Precautions for modifications: Decorative items such as rearview mirrors, small stickers, and small spoilers do not require registration after modification. However, changing the color or replacing rims and body kits must be registered. During modification, the original body structure and electrical wiring of the vehicle must not be damaged to prevent safety hazards.

I've been driving for nearly twenty years and know full well that modifying taillights requires careful handling. In China, vehicle modifications are strictly regulated. According to the 'Motor Vehicle Safety Inspection Standards,' the color, brightness, and flashing frequency of taillights must comply with national standards. If you casually install those flashy lights with insufficient brightness or colors like blue or green, it constitutes illegal modification. Traffic police will issue fines upon discovery, possibly deduct points, or require you to revert to the original setup. A friend of mine recently learned this the hard way—he installed a cheap knockoff light, failed the annual inspection, and wasted money redoing it. Safety comes first; unclear light signals significantly increase the risk of rear-end collisions. So, I recommend checking regulations before modifying or going to an authorized repair shop for documentation—don't risk it to save money.

I'm a car modification enthusiast who loves tinkering with the exterior, but when it comes to taillight modifications, it's crucial to understand the legal boundaries. Whether it's legal or not depends entirely on compliance with regulations. The law requires taillights to be red, with uniform brightness and not overly dazzling to avoid affecting other drivers. Switching to LED lights is generally fine, but adding smoke effects or blue light filters violates the rules. In my car enthusiast group, several friends have been fined for failing inspections after modifications, having to pay extra to revert to factory settings. From a safety perspective, non-compliant lights can confuse following drivers about brake signals, potentially causing accidents. My advice: if you're considering modifications, opt for reputable brand products—don't cut corners—and ensure the lights meet national standards before proceeding.

I've been repairing cars for several years and have seen many clients run into trouble with tail light modifications. Illegal modifications mainly refer to altering the brightness or color parameters of the lights, such as changing red lights to pink or blue, or making them too dim to see clearly. These violate regulatory standards and will cause issues during the annual vehicle inspection at the DMV, requiring reinstallation and potential fines. The safety risks are even greater, as signal confusion can easily lead to rear-end collisions. Rather than spending money on a costly lesson, it's better to consult professionals beforehand to ensure the light parameters meet the required standards.
