What color should clearance lamps be for large vehicles?

Clearance lamps for large vehicles are required to be amber in color. This specification is important for visibility and safety on the road. Amber lamps indicate the edges of the vehicle, providing a visual reference for other drivers, particularly in low-light conditions or bad weather. The use of amber color helps in distinguishing these lamps from other types of vehicle lights, such as those used for turn signals or brake lights, which may serve different purposes and have different color requirements.

The regulations around vehicle lighting are designed to enhance safety by ensuring consistency and clarity in the signaling of vehicle dimensions and intentions to other road users. Adhering to these regulations helps prevent accidents by clearly indicating the presence of large vehicles and their overall length, width, and height.
