The use of brake + turn signal tail lights and side marker lights can dramatically increase the visibility of your truck. These lights can make the truck more visible to other vehicles and reduce the risk of other drivers colliding with the truck. Helps to improve the safety of traffic flow.
Brake and turn tail lights help other vehicles anticipate the truck's movement, reducing the likelihood of traffic accidents;
Blind spots often exist on the sides of trucks. The location and arrangement of side marker lights can indicate the length of the truck, helping other drivers to better understand the size of the truck and thus better plan overtaking or lane-changing behavior.
