Loading... Please wait...No trailer or 5th wheel should be without this great diagnostic tool. It will check the lights and diagnose any problems that may occur. Simply plug your 7 Pin Adapter into the Light Check and get a reading. You will know in seconds if your lights are working and if not what the problem is. Works with all lights including LED's.
Can also be used as a Safety Device---it will illuminate your trailer lights without a tow vehicle connected. In the event you are stranded on the road and need to disconnect your tow vehicle, the LightCheck will keep your rig's lights on in safety mode.
There is nothing on the market like the LIGHTCHECK! If you tow you need one!
