A lens cover for covering the lens of a traffic signal when the signal is not in service. The lens cover is made of a black polyethylene flat tubing which is cut and sealed on one end and has an open end to fit over traffic light lens shields. The lens cover is completely opaque and thus prevents light from the lens passing through. Thus, motorists are not confused with respect to the traffic light being in an operating state. The lens cover also has an observation hole at the bottom which allows one to check the operation of the traffic light from ground level.
