Can modified xenon bulbs pass the annual inspection?
2 Answers
Self-modified xenon bulbs can pass the annual inspection if they are equipped with lenses and have a color temperature below 6000 lumens. Those without lenses will not pass the inspection. Some relevant information about modifying xenon bulbs is as follows: 1. When choosing xenon bulbs for modification, the first thing to consider is the tube. Select one with a smooth surface, straight alignment, and uniform thickness. 2. It is recommended to follow relevant regulations when modifying xenon lights. Do not install bare xenon bulbs; add lenses if necessary. 3. Good xenon bulb brands from abroad include Philips and Osram, but due to cost factors, these international brands generally pay little attention to the domestic modification market.
I learned from my friend at a car modification shop that whether you can pass the annual inspection after installing xenon bulbs mainly depends on whether the modification meets the standards. Xenon lights are bright, but without a proper lens, the light scatters everywhere and becomes unbearably glaring, which will definitely fail the inspection. The inspectors use specialized tools to measure the focus and brightness of the lights, with the standard being not to affect others' vision. I once tried modifying them carelessly and failed the inspection, then had to spend money readjusting them. If you want to modify them, I suggest going to a professional shop to ensure the lens is properly installed and the color temperature is around 4300K—don’t cut corners to save money. Road safety comes first, so check the local inspection requirements before modifying to avoid wasted trips. Also, some regions are strict, outright rejecting blue or overly bright white lights, so stick to compliant ones. This is tied to driving safety—don’t risk big losses for small gains.
