So my little boys asked me if I could put Christmas lights on the outside of our vehicle (their friends parents have done this on their SUV's) and want me to do it as well. I know there is a AC power inverter located in the rear of the vehicle, but every time I plug 1 string of lights into it, the switch just clicks and no power to the lights. Am I missing something? The last thing I want to do is blow my electrical system up but I wouldn't think one strand of lights is too powerful for this switch. Any help would be greatly appreciated!! Thanks!
