Modifying car lights does not require registration. The general reasons why modified car lights may fail the annual inspection are as follows: 1. Non-compliant modifications: During the annual inspection, the vehicle's appearance must match that on the vehicle registration certificate. Excessive modifications may result in failure. However, modifications to the internal components of the car lights, as long as the light projection meets regulations, will not be affected. 2. Light brightness: As is well known, everything has a usage cycle, and car lights are no exception. They naturally age, leading to dim lighting. Some may also use substandard bulbs, resulting in insufficient brightness. Regardless of the reason, if the light brightness is insufficient, it will fail the annual inspection. The annual inspection requires that the low beam must not be less than 1050 lumens, and the high beam must not be less than 1450 lumens. If the bulbs used are excessively bright, this may also cause the inspection to fail. 3. Light projection angle: The angle of car light projection is strictly regulated by national standards to prevent glare and avoid causing harm to other vehicles or pedestrians.

I recently replaced my car's headlights with LED ones, and the brightness has improved significantly. But someone asked me if I needed to register the modification. As far as I know, in China, modifying car lights generally requires registration; otherwise, it's considered illegal modification. If you don't register, the police can fine you 200 yuan and deduct points if they catch you, and your car won't pass the inspection. Once, my friend was too lazy to register, and he got pulled over at night because the light was too glaring and affected safety. He ended up spending extra money to reinstall them. The registration process is quite simple: after changing the lights, go to the vehicle management office for an inspection to confirm that the light angle and intensity meet the standards, and then you can register the changes. Safe driving is the most important thing—don’t rush modifications to avoid accidents. Personally, I recommend consulting a professional repair shop or the vehicle management office before making any changes to avoid DIY violations, as driving with non-compliant lights poses high risks.

As a car enthusiast who has modified headlights on several vehicles, I can confidently say that headlight modifications must be registered. Failing to do so is not only illegal but may also result in a 200-yuan fine and affect your vehicle insurance record. For example, last year I forgot to register after installing HID lights, which caused my vehicle inspection to fail, wasting time and effort on rework. The registration process involves driving the modified vehicle to the DMV, where professionals check if the light pattern meets standards. Ignoring this step increases accident risks, as non-compliant lighting can dazzle others and cause collisions. Choosing compliant accessories is crucial. I recommend making it a habit to register immediately after modifications—playing by the rules ensures peace of mind. While fun is important, safety details should never be overlooked.

I just bought a car and want to modify the headlights to make them brighter. After consulting some experienced drivers, they said that modifying headlights requires registration to be legal. In China, failing to register is considered illegal, and traffic police may impose fines and deduct points if caught. I looked it up and found that registration is to ensure the lights meet standards and guarantee safety for night driving. The process is simple: take the car for registration after modification. As a beginner, I think safety comes first. Before making any changes, I plan to seek help from a repair shop to avoid violations and save trouble later.

Safety first, modified car lights must be registered. Unregistered lighting may cause glare and lead to accidents, as regulations require inspection and approval. A 200-yuan fine is minor, but causing harm is serious. I recommend completing the registration immediately after modification—just drive to the DMV for a one-time test. Ignoring this raises the risk of failing annual inspections, endangering yourself and others.
