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

[LeAngela]

Headlights, clearance lights, and rear position lights are introduced as follows: 1. Clearance lights: From the literal meaning, "clearance" means warning, and "light" refers to the outline. Therefore, clearance lights are warning lights used to alert other vehicles. They are generally installed on the edges of the car roof, indicating both the height and width of the vehicle. According to safety standards, vehicles taller than three meters must be equipped with clearance lights. The color of clearance lights is white at the front and red at the rear. 2. Rear position lights: Mainly used to indicate the presence and approximate width of the vehicle, facilitating other vehicles in judging during overtaking or meeting. They are installed at the rear of the vehicle and automatically emit red light when the vehicle brakes. 3. Headlights: The headlight assembly is one of the important components ensuring the safe operation of a vehicle. The farther the headlight illuminates and the better its light distribution characteristics, the higher the safety performance of the vehicle.

Headlights are what we commonly refer to as the front headlamps, used to illuminate the road ahead while driving. They're essential at night or when entering tunnels. Position lights are located on the outermost sides of the vehicle. When I first started driving, I often confused the two. Front position lights are on both sides of the front, while rear position lights are on both sides of the back, mainly to help others see the width of the car. The rear position lamp is right at the back of the car, glowing red at night to alert vehicles behind not to collide. Once, during rain, my rear position lamp malfunctioned, and I was nearly rear-ended. These lights might seem insignificant, but each plays a crucial role in driving safety. Beginners are advised to find an open space to test all the switches, feel the difference in light positions and brightness, and they'll easily distinguish them once familiar.

Headlights are responsible for basic illumination, clearance lights manage the display of the vehicle's outline, and rear position lights provide position indication at the rear—these three types of lights complement each other and are indispensable. Headlights are located in the middle of the front of the vehicle, emitting a concentrated beam forward when turned on. Clearance lights are installed at the outermost edges of the front and below the side mirrors, making them particularly visible from the side. Rear position lights are essentially the constantly lit red sections within the taillight assembly, most noticeable when following another vehicle at night. As a mechanic, I often see car owners confusing clearance lights with rear position lights. In reality, clearance lights primarily allow vehicles on the side to see you, while rear position lights are for positioning by vehicles directly behind. If modifying vehicle lights, note that clearance lights must be white or amber, and rear position lights must be red—these are mandatory regulatory requirements.

After five years of driving, I finally got these lights sorted out: The headlights are the big bulbs in front of the car, used for low beam and high beam. The clearance lights are at the four corners of the car body, lighting up like a golden edge, especially useful when parked on the roadside at night. The rear position light is fixed in the center of the rear, emitting a gentler red light than the brake light, continuously indicating your position. I remember the driving instructor emphasized during the test that in rainy or foggy weather, you must turn on both front and rear clearance lights and the rear position light, and if visibility is less than 100 meters, you also need to add fog lights. I used to think clearance lights were unnecessary until one time on a mountain road when an oncoming car only had its headlights on, making it impossible to see the width of the car, and that's when I realized the importance of clearance lights.
