Boat trailer light de-energization means
Abstract
Abstract A control module including circuitry therefor, which prevents short circuit conditions of a boat trailer's light-circuitry at the boat-launch site, in which at least two co-ordinated control circuits are provided to assure that none of the trailer circuits are energized while the trailer is in the water body of the lake or stream at the launch site. Both the circuits are provided as branches of the towing vehicle's own circuitry. One is provided to be a branch of the vehicle's backup lights' circuitry, utilizing the fact of the boat-launch and retrieval maneuver normally including a reverse-drive action of the towing vehicle, which assures energizing of that first control circuit. Another control circuit is provided as a branch of the towing vehicle's taillight circuit, and a control module includes switches for opening all the boat trailer circuits with a control which provides that for its intended operativity both those control circuits must be energized simultaneously, thus minimizing chances of inadvertent de-activation of the trailer's light circuitry when needed for highway use; and also included is a short-time delay circuit which provides against inadvertent de-activation of the trailer's light circuitry by the vehicle's gearing merely passing through "reverse" setting in shifting through that setting while the vehicle's taillight circuitry is energized.
