What are clearance lights?
1 Answers
Clearance lights, also known as marker lights, are indicators installed on vehicles to show the width of the vehicle. Below is relevant information about marker lights: 1. Introduction: Marker lights are the outermost lights at the front and rear of a vehicle. Large trucks also have marker lights on the roof and sides. The term 'marker light' can be understood literally: 'marker' means warning, and 'light' refers to the outline. Therefore, marker lights are warning lights used to alert other vehicles. Installed along the edges of a vehicle's roof, they indicate both the height and width of the vehicle. 2. Regulations: Safety standards require vehicles with a height exceeding three meters to be equipped with marker lights. The color of marker lights is white at the front and red at the rear. Based on existing products like the Steyr truck and in compliance with regulations: GB7258 'Technical Requirements for Safety Operation of Motor Vehicles' Section 8.2.6 states that vehicles with an unladen height exceeding 3.0m or a width exceeding 2.10m must be equipped with marker lights; GB4785 'Regulations for Installation of External Lighting and Signaling Devices for Motor Vehicles and Trailers' Section 4.3.17 specifies requirements for the number, configuration, layout, color, installation position, and circuit connection of marker lights. Without altering the existing connection method, adding a red light distribution surface to the back of the front marker light incorporates the function of a rear marker light. This approach eliminates the need for additional installation positions on the cab and reduces costs.
