ABSTRACT:
An intersection safety light assembly and method for warning a driver of a vehicle on a first road of an approaching vehicle on a second road which is approaching an intersection of the first and second roads. The method includes a housing that has a peripheral wall and a top wall. The housing is mounted adjacent to the intersection and is positioned such that a clear line of sight exists between the housing and a blind spot of the intersection and between the blind spot and the first road. A motion detector is mounted on the peripheral wall and is directed toward the blind spot. A light emitter is mounted on the peripheral wall and is directed toward the first road. The light emitter is electrically coupled to the motion detector and is turned on by the motion detector when motion is detected in the blind spot. A power supply is electrically coupled to the motion detector.
