Abstract
Abstract A flasher controller for vehicle warning lights that comprises a housing for a circuit board that electrically controls the device. The apparatus includes a mounting strap of conductive material which includes an internal ground connection with the circuit board and a mounting flange external of the housing that functions as the external ground connection for the circuit board. The housing is filled with a resinous material that functions as a weatherproof seal, as well as means for securing the mounting strap to the housing. The device is adapted to automatically sequentially operate and flash either amber or red warning lights on the vehicle in accordance with a plurality of selectable programs. The control functions are effected entirely by solid state electrical components which are potted together with the mounting strap.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
176 words
A controller for sequentially operating a plurality of vehicle lights comprising, in combination a circuit board housing including spaced sidewalls and a bottom wall forming a cavity; a circuit board positioned in the cavity and including a circuit board ground terminal; an electrically conductive mounting and grounding means including an internal flange forming a second ground terminal engaging said circuit board ground terminal, an intermediate flange extending to the exterior of said cavity, and an external flange extending beyond a side wall and forming a housing supporting mount for connection with a vehicle in grounded relationship therewith; a plurality of upstanding conductors, each of which includes a lower end mounted on the circuit board and an upper end connector for attachment to external circuit elements, said conductors comprising the following: 1. battery conductor, 2. amber light conductors 3. red light conductors 4. start switch conductor, 5. door switch conductor, and a resinous insulating and sealing material within said cavity in sealed surrounding relationship with said engaging ground terminals and said lower ends of said upstanding conductors.
