Abstract: An add-on housing circuit usable with an existing garage having a switch controlled overhead incandescent screw type lamp socket and a conventional remotely controlled garage door opener with the same type of incandescent lamp socket. This housing has internal circuitry and an outer display panel and is operatively connected to an added fluorescent lighting fixtures within the garage in place of the conventional incandescent bulbs in the garage and opener. Either one or two electrically operated garage door openers may be used with the housing and fluorescent lighting fixtures. The housing's display face has visual indicators which indicate that the existing garage wall switch is operating to supply power to a fluorescent lighting system or that electrical power from the existing garage opener is received. If two garage doors and openers are used, then an additional visual panel indicator to indicate the operative state of the second door with supporting internal housing circuitry included.
