Can car headlights be changed to LED?

Sedans with modified LED headlights can pass the annual inspection. The light intensity and brightness of the upgraded LED headlights on sedans comply with national standards. There is also a height inspection, and the upgraded LED headlights are usually adjusted accordingly, which also meets the requirements. Below is some additional information: 1. Vehicle annual inspection: It refers to a mandatory inspection for every vehicle that has obtained an official license plate and registration certificate, equivalent to an annual physical examination for the vehicle according to the "Technical Conditions for Motor Vehicle Operation Safety." Vehicle annual inspections can promptly eliminate potential safety hazards, encourage enhanced vehicle maintenance, and reduce the occurrence of traffic accidents.
Just helped a friend upgrade to LED headlights the other day, which is actually a pretty common modification. But do pay attention to legal regulations - many places now require color temperature not exceeding 6000K, otherwise it definitely won't pass annual inspection. When I did the upgrade, I specifically chose 5500K warm white light, which triples the brightness without being glaring. The most crucial part is installing projectors, otherwise the scattered light will blind oncoming drivers - I learned this the hard way during my own installation. Also need to check if the original car has a decoder interface, as power mismatch will trigger error codes. Nowadays good LED lights can last up to 50,000 hours, meaning you'll never need to replace them before the car's scrapped, though you should budget around 700-800 RMB for quality ones.
As a professional in the automotive parts industry with exposure to thousands of modification cases, here's the straightforward conclusion: For private vehicles (excluding trucks and special-purpose vehicles), LED conversion is completely legal. During modification, the original lamp socket structure must be retained, and low beams must be equipped with lenses to prevent glare. We recommend opting for 36W models with cooling fans, which offer three times better heat dissipation than standard versions. Last month, while working on an old Focus conversion, we found that a decoder was necessary to eliminate dashboard warnings. Special reminder: During rainy seasons, regularly check the sealing of light assemblies – our shop has encountered multiple cases of water ingress due to aged sealing rings.
