"Light Buster Trailer Hitch Accessory Light"
Light Buster is a dual function backup or utility light
which plugs directly into any 7 way round RV/Trailer receptacle.
Use it in the backup mode, and every time you put your vehicle
in reverse, 50 watts of bright, white light illuminates everything
behind you. Switch to utility with your running lights on and it stays
on. For more info, check out our web site. Great for contractors,
hunters, snow plowers, SUV owners. No drilling or wireing needed.
