Flexbilt offers LEDGlow's Add-On Magnetic Power Switch allows you to power the truck bed lights on by simply opening your truck's tailgate. When you're done using the lights, close the truck's tailgate and the magnetic switch automatically cuts power to the kit and turns the lights off. The magnetic power switch and magnetic receiver must be mounted within 5mm of each other and will not interfere with the operation of the tailgate. This automatic switch features 3' of wire, magnetic receiver, 3M tape, 4 self-tapping screws and installation instructions. LEDGlow includes free lifetime technical support and a one year limited warranty with each purchase.
