control of reverse light of the trailer working with LED and bulb lamps and PWM steering recognition of PWM steering of car lamps (analogue method) working with LED and bulb lamps on the trailer directly steering of fog-light of trailer

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 G13-8 but can be used with G7 (in this case without REV 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).
