Automotive lights, acting as the "eyes" of a vehicle, are a crucial factor in driving safety. Below are the main types of automotive lights and their functions:

 

Headlights:Headlights are among the most important lights, primarily used to illuminate the road ahead and improve visibility at night or in low-light conditions. They also help enhance vehicle visibility and alert other road users to ensure safety.

 

Taillights:Taillights primarily provide visibility to vehicles behind, warning and alerting other road users to ensure safety. Brake lights are particularly important; when a vehicle brakes, the brake lights illuminate to promptly inform following vehicles to ensure safety.

 

Turn Signals:Turn signals are used to indicate a vehicle's turning or lane-changing intentions. By flashing these lights, they convey driving intentions to other vehicles, contributing to safe driving.

 

Fog Lights:Fog lights are primarily used to provide additional illumination in rainy or foggy weather, enhancing visibility. Fog lights have high brightness and strong penetrating power, helping to improve vehicle visibility in adverse weather conditions such as fog, haze, rain, and snow.

 

Side marker lights: Side marker lights are installed at the four corners of the vehicle and are mainly used to display the outline of the vehicle at night or in low light conditions, thereby improving the visibility of the vehicle.
