What are headlights, clearance lights, and rear position lights?

[DeColton]

Here is the relevant introduction about headlights, clearance lights, and rear position lights: 1. Headlights: Headlights refer to the lighting devices installed on both sides of the front of a car, used for road illumination during nighttime driving. They can be categorized into two-lamp and four-lamp systems. The illumination effect of headlights directly affects nighttime driving operations and traffic safety. 2. Clearance lights: Clearance lights are warning lights used to alert other vehicles. They are usually located at the outermost edges of the front and rear of the vehicle. Large trucks also have clearance lights on the roof and sides. 3. Rear position lights: Rear position lights, along with front position lights, are commonly referred to as small lights or width indicator lights. Their main purpose is to indicate the presence and approximate width of the vehicle, helping other vehicles judge during encounters and overtaking.
