Abstract:
1. A trailer light adapter that is adapted to supplying signals to operate lights of a towed vehicle from modulated signals of a lighting circuit of a towing vehicle, said adapter comprising: at least one input that is adapted to receive a pulse-width modulated signal from the lighting circuit of the towing vehicle and at least one output that is adapted to supply an output signal to operate a light of the towed vehicle; a decoder that is adapted to decode the pulse-width modulated signal and to provide a decoded signal indicative of a desired state of the light of the towed vehicle, wherein said decoder determines an average voltage of said pulse-width modulated signal to supply the decoded signal; and a power circuit that is responsive to the decoded signal and is adapted to supply the output signal to operate the light of the towed vehicle.
