A 2" x 4" oval bullseye-style clearance/marker light with an amber lens, used on trucks and trailers to indicate vehicle width and outline at the front, rear, or sides. The bullseye lens design projects light visibly from multiple angles for improved night visibility, and the amber color is used per standard lighting color codes for side/front marker positions. It's typically surface-mounted and used to meet DOT marker light requirements for commercial vehicles.
