Need a dependable electrical link between your towing vehicle and trailer? This 3-pin 12V trailer plug delivers a stable connection for the basic lighting signals every time you hit the road. The three poles cover the essential lighting functions, so drivers behind you clearly see your intentions. A sturdy plastic housing shields the inner contacts from dust and moisture in everyday use.

A protective cap keeps the contacts clean when the trailer is unhooked. Thanks to its simple shape, the plug seats firmly and stays put while driving. You save both time and the cost of a workshop visit.
