Check to be sure you have a "hot" wire hooked into your truck plug, and that the fuse is in the line. Most interior lights are wired separately to the "hot" or "accessory" post, and will work as long as the trailer is plugged into the truck.

"99" Dodge always on... "03" Dodge the same.....check for power at bumper receptical...if none check fuse... If you do have power at bumper Check plug and see if it wired correctly then you can work back from there.
