The LIGHTCHECK & SAFETY PLUG has been designed to make checking the lights on your trailer or 5th wheel a snap. It turns the job into a one person job. You will no longer have to plug your unit into the tow vehicle to see if the lights are working. No more hand signals. No more walking from the front of the vehicle to the back of the unit! Just plug the 7 pin electrical plug from the unit into the LIGHTCHECK and the lights on your unit will come on, allowing you to do a walk around and see what’s working and what’s not. The turn signals, brake lights and the amber warning light on LIGHTCHECK will blink. The clearance lights will remain lit. There
must be a charged battery on the unit for the LIGHTCHECK to perform this check. THE LIGHTCHECK WILL ALSO WORK WITH L.E.D. LIGHTS!
