Clearance Lights
Clearance lights are small, amber or red lights mounted on the sides and/or top edges of a trailer. Their primary function is to outline the trailer’s width and height, making it easier for other drivers to gauge its size, especially at night or in low-visibility conditions. These lights are essential for safety, helping to prevent collisions and ensuring the trailer is more conspicuous on the road.
Marker Lights vs Clearance Lights
Both marker lights and clearance lights serve important safety functions on trailers, but they have distinct purposes and placements:
Marker Lights:
- Indicate the presence and outline of the trailer.
- Placed along the sides and rear.
- Typically amber or red.
- Help other drivers see the trailer’s dimensions and avoid collisions.
Clearance Lights:
- Specifically highlight the width and height of the trailer.
- Mounted on the top edges and corners.
- Usually amber in the front and red in the rear.
- Ensure that the trailer’s boundaries are visible, especially in low-light conditions.
While both types of lights aim to increase visibility and safety, marker lights provide a general outline, whereas clearance lights specifically denote the trailer’s clearance dimensions.
