WH0 module is simplest module of trailer steering of the light and is most economically.

Module was designed to connect to the 8-wire installation of the trailer (this include REV light) and should be used with 13-pins socket but can be used with 7-pins socket (in this case without REV light).
WH0 module works correctly with lamps based on filament bulb or on LED in car. Additionaly, it works with PWM steering of lamps in car (when by one wire are controlled two lights - eg. "brake lights" and "tail light").

This is simplest module with minimal accessories for lowest price.


NOTE: package don't include a socket (for the trailer) nor output wires (to the socket, to the power).
