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.

I'm quite familiar with the headlight inspection items from a practical perspective. First, check the light intensity to ensure brightness meets standards; second, examine the beam distribution pattern to verify proper switching between low and high beams. The angle and height test prevents lights from being too high (overly dazzling) or too low (poor visibility). Color consistency confirms the absence of harsh color temperatures. Alignment adjustment ensures symmetrical left and right lights without deviation. I also pay attention to smooth switch functionality, stable relay and circuit connections to avoid short circuits. Regular inspection of these items is crucial—it saves repair costs and enhances driving safety. For DIY checks, simplified steps like using a ruler to measure height work, but professional equipment yields more accurate results.

Headlight inspection involves multiple items. The core is brightness measurement, which must meet specified intensity standards. Beam angle and height checks prevent hazards caused by substandard lighting. Pattern testing evaluates whether the switching between low and high beams is smooth. Color verification ensures the color temperature stays within the specified range. Alignment settings check whether horizontal and vertical alignment is balanced. Switch and control mechanism inspections include verifying the integrity of relays, plugs, etc. These inspection items help avoid nighttime accidents, and it is recommended to conduct a comprehensive inspection regularly for self-protection.
