Abstract: A cup-shaped lower base adapted to have an upstanding viewing lens mounted thereon has a strip-like internal assembly bracket therein. The bracket has a vertically extending lower mounting end portion secured adjacent a base sidewall upwardly connected to a vertically and inwardly angled intermediate portion terminating upwardly in an inwardly projecting socket end portion generally centralized relative to the lens. A socket is attached projecting upwardly from the bracket socket end portion, a first electrical component such as a flasher is attached to the bracket intermediate portion and the bracket mounting end portion has a generally horizontally extending mounting tab on which is mounted a second electrical component such as an audiblizer, all of the socket and electrical components being operably electrically connected for proper actuation. In assembly, the socket and electrical components may be preassembled on the bracket exterially of the base and then assembled as a bracket unit in the base.
