Which light is the clearance light?

[MacElizabeth]

Clearance lights are the outermost lights located at the front and rear of a vehicle. Large trucks also have clearance lights on the roof and sides. These lights serve as warning signals to alert other vehicles, installed along the edges of the vehicle's top to indicate both its height and width. The clearance light is designed based on existing Steyr vehicle products in compliance with regulations. According to the technical requirements for safe operation of motor vehicles, any vehicle with an unladen height exceeding 3.0m or a width exceeding 2.1m must be equipped with clearance lights. The installation regulations for external lighting and signaling devices of automobiles and trailers specify the quantity, configuration, layout, color, installation position, and circuit connection requirements for clearance lights.
