What are the inspection items for car lights?

Car light inspection items include checking the front left and right turn signals, fog lights, parking lights, high beams, low beams, and dimming lights. The rear inspection includes left and right turn signals, parking lights, brake lights, reverse lights, and license plate lights. Below is a detailed introduction to car light inspection items: 1. Headlights: When inspecting the low beam irradiation position of headlights, the headlights should be placed 10m in front of a screen, and the height of the cutoff line or midpoint should be 0.6H~0.8H (H is the reference center height of the headlight). The horizontal position deviation should not exceed 100mm to the left or right. 2. High and low beams: For cars equipped with dual-beam lights (high and low beams), the adjustment should focus on the low beam. For lights that can only adjust the single-beam high beam, adjust the single-beam high beam.
I've been driving for twenty years and have developed a habit of checking the lights. Mainly, I check if the switching between low and high beams of the headlights is functioning properly and if the brightness is sufficient to see the road clearly in dim light. Then, I make sure the taillights illuminate when braking, especially during emergency braking, and that the turn signals flash at a consistent rate—not too fast or too slow. I test this with the key switch. The license plate light should clearly illuminate the plate number at night to avoid being caught in unclear violations. Before using the fog lights in rainy weather, I ensure they work and clean the dust and dirt off the lens, as it can affect light dispersion. Additionally, I check that the interior lights turn on and off smoothly, especially the reading light. Every three months, I spend a few minutes doing a round of checks. If a bulb is aging or there's a wiring issue, catching it early can save a lot on repairs and prevent potential hazards. Safety comes first—don't underestimate these details. Drive enough night roads, and you'll understand their importance.
