Abstract
A trailer signal converter includes a plurality of inputs, including a first towing vehicle turn light signal, a second towing vehicle turn light signal, and a trailer brake signal. The trailer brake signal is a pulse-width modulated signal. The trailer signal converter selectively drives the turn and stop light signals on the trailer based on the input signals. In a three-wire system, the signal converter is configured to receive a brake signal input and a brake light input and selectively drive the trailer stop light signals.
