Abstract
A lens for preventing the build-up of snow and ice on LED traffic lights. The lens is hollow and fits over the LED signal beacon of the traffic light. The lens has a sidewall defined by a right circular conical frustum between a circular base and a plane spaced apart from the base and oriented at an oblique angle to the base. A convex face portion of the lens extends from the sidewall and closes the hollow space within the lens.
