A combined clearance and marker lamp comprising a generally rectangular housing having a base wall and a peripheral wall surrounding the base wall and having side wall portions and end wall portions. Longitudinally spaced light bulbs are mounted in the housing with at least the filaments of the bulbs beneath the plane of the upper edges of the peripheral wall of the housing. A lens of transparent material is mounted on the housing and has a top wall, side walls and end walls telescoped over the side and end wall portions of the housing. The top wall of the lens has longitudinally spaced sets of arcuate ribs on the inside surface thereof. The top wall has a prism on the inside surface of the top wall adjacent each end wall of the lens for directing light from the bulbs longitudinally outwardly through the end walls. Each side wall of the lens has a second prism on the outer surface thereof to direct the light longitudinally of the lamp. |
