Loading... Please wait...This revolutionary product allows you to easly and quickly test for the proper function of your trailer lights. It also acts as a troubleshooter to let you know what the problem is, so no more frustrating single wire checking.
The Light Check 2 is designed for Tractor Trailer applications or other trailers that do not have a battery on board. It uses a standard cigarette lighter plug to power the test mode. No need to hook up your rig to test the trailer lights.
