WTM500 Trailer Trigger Module


The Trailer TriggerTM is the most advanced, compact and easiest module to eliminate problems with lighting when connecting late model vehicles to trailers. Vehicles with advanced electronics which control rear lighting functions can cause LED lighting to pulse or flash once a trailer is connected. False bulb out warnings and error codes may also appear in some vehicles. The Trailer TriggerTM can be installed either on the trailer or vehicle to eliminate these problems instantly. By using proprietary circuitry the Trailer Trigger™ ensures correct operation of LED lighting when the trailer is connected to modern vehicles. The main module is totally weather proof and measures just 35x35x 20mm with screw mounts making it ultra easy to mount on the A-frame or near the tow bar. The wiring has been specifically designed so that the connections can be simply wired into the trailer connector. The Trailer Trigger™ is computer safe and is the perfect solution for pulsating LED lights on trailers.
