How to replace licence plate bulb ?

Ok I’ve done this . The bulb is a sealed LED unit you can buy from Superbright LED order LPC-B-NW2 . It’s held up by 2 screws and the 2 wires should have some slack . Warning ⚠️ don’t pull too hard as NuCamp uses splice connectors which are not very strong. I called NuCamp for advice and they told me too pull it out , it came out and the mating wires could not be accessed through the 1/2” hole. When you take it down capture the 2 wires and cut them off against the housing which should give you enough wire to mate to the new fixture. You can use wire nuts to connect the wires , and electrical tape to secure nuts for safety. Or look up  on the web TapCon connectors these I prefer. 
In closing if you have to find the wires you will have to remove the hinged shelf across the rear, behind the seat back. It’s only held in place by a few square drive screws and the hinges . Let me know if you need clarification. Good luck
