Headlight inspection includes left and right turn signals, fog lights, small lights, high beams, low beams, and dimming lights. There are three main inspection items for headlights: high beam luminous intensity, high beam vertical offset, and low beam vertical offset. Headlight inspection scope: LED headlights, halogen headlights, automotive headlights, focused headlights, projection headlights, etc. Headlight inspection items: Brightness inspection, light intensity inspection, illuminance inspection, lighting distance inspection, anti-glare inspection, color temperature inspection, high-temperature resistance inspection, light aging test, continuous lighting lifespan test, focusing inspection, sealing inspection, environmental durability testing, etc.
I often check my car's headlights myself. There are quite a few items in headlight inspection, mainly to ensure safe nighttime driving. Brightness testing is the most basic - you need to measure whether the lights are bright enough, as insufficient brightness can affect visibility. Beam height and angle checks are also important to prevent glare that could dazzle other drivers. Regarding color, the light must be white or pale yellow - lights that are too blue may violate regulations. Alignment testing includes both horizontal and vertical directions to see if adjustments are needed. There are also detailed items like checking switch responsiveness, looking for short circuits or poor contacts in the wiring, and verifying fuse integrity. Overall, performing these inspections regularly can reduce accident risks and extend bulb lifespan. I once got fined for lights that were too bright, so now I check annually.
