To permit convenient attachment of a warning lighting system to the stop sign of a school bus, U or channel-shaped brackets for warning lamps are hinged to each other at adjacent sides so that the lighting system may be positioned around the edge of the stop sign to mount lamps housed in solid translucent plastic thereto. Because the lamps are encased in relatively thick plastic, they project from the channel shaped bracket and nonetheless withstand the shock of the stop sign banging against the bus or vibrating with the motion of the bus. The lamp may be constructed to serve other purposes which require the solid plastic encasing for sturdiness and waterproofing, such as: (1) mounting on the top of the pole of a bike with pin inserts; (2) magnetic mounting to the body of a car; or (3) to be immersed in water for fishing.
