A plurality of light emitting diodes are mounted on a base that encircles or surrounds a primary vehicle light source such as a headlight, a taillight, a turn signal light or the like. A control circuit senses when the primary light source fails to provide the requisite light, and applies power to the light emitting diodes so that the vehicle can continue safely without loss of the function served by the primary light source. Additional diodes may be provided on the base to serve an ornamental function.
