Learn About Different Types of Lights Used in Trucks and Their Functions

Various types of lights used in trucks play a crucial role in ensuring safety, visibility, and proper communication. Headlights and fog lights help drivers see the road in low or foggy conditions, while tail lights and brake lights inform vehicles behind about the truck's presence and speed changes. Turn signals and hazard lights notify other drivers about the truck's direction or emergencies. Reverse lights illuminate the rear area, and side marker and cab lights enhance the truck's size and position visibility. Proper use and maintenance of these lights are essential for preventing accidents and ensuring safe driving.
