Abstract:

An electrical taillight adapter circuit (6) interfaces a three-lamp vehicle lighting circuitry (2) with a two-lamp trailer lighting circuitry (6). The vehicle lighting circuitry primarily includes a group (10) of three right hand lamps (20, 22, 24) and a group (12) three of left-hand lamps (12). These lamps operate in response to signals generated by the vehicle operator, and are electrically connected to the adapter circuit. The trailer circuit generally includes a group (14) of two right hand lamps (34, 36) and a group (16) of two left-hand lamps (35, 37). The adapter circuitry receives electrical signals from the vehicle circuit (2), processes them, and outputs power to the appropriate trailer lamp. This electrical taillight adapter circuit (4) interfaces the nonconforming taillight circuit of a vehicle with that of a trailer, while providing the trailer lamps with improved output current and protecting the system from short circuit conditions.
