How Many Types of Lights Does a Sedan Have?

Automotive lighting mainly includes headlights (comprising high beam and low beam), front position lights, rear position lights, license plate lights, instrument panel lights, turn signals, brake lights, hazard warning flashers, reverse lights, and front fog lights. Below are the relevant introductions: 1. The front-end headlights are divided into low beam and high beam. High beam is used in situations with very poor lighting and no auxiliary light sources, while low beam is used during relatively bright nights. 2. Fog lights are used when road conditions are not very clear, such as during foggy weather when visibility is poor. These lights are located at both the front and rear of the vehicle, with only one on each side, asymmetrical, and differentiated from other lights of the same color. 3. Brake lights illuminate when braking and are typically installed at the rear end of the vehicle, in a conspicuous red color. Additionally, there are reverse lights, which are positioned at the rear end of the vehicle, on either side of the trunk. The two types of lights differ in color, with reverse lights being white.
As a veteran driver with twenty years of experience, I have witnessed the evolution of various car lighting systems. Car lights can generally be divided into three main categories: illumination, signaling, and auxiliary. The most commonly used are the headlights, including low beam and high beam, which illuminate the road at night; signaling lights are particularly important, such as turn signals to indicate the direction of a turn, and hazard lights to warn vehicles behind during an emergency stop. There are also brake lights that illuminate when the brake is pressed, alerting the rear to avoid a collision. Auxiliary lights like fog lights can penetrate rain and fog, reverse lights automatically turn on when backing up, and daytime running lights make the car more visible during the day. Inside the car, there are also lights like reading lamps. Each of these lights serves a specific purpose, and understanding their functions is crucial for daily driving and safety in critical moments.
