Select Clearance Lights and Marker Lights Are Not Working

Question:

All the lights on my camper work except the marker lights in back and to the side. The two clearance lights work in the front. But the 5 on the back and 2 red lights on the side dont work.

The marker lights and clearance lights on your trailer should all be tied into the same circuit with a jumper wire ran to each of them. Therefore, if there are some working but some that are not then this leads me to believe that there is either a short in the running light wire or burnt out bulbs. The bulbs are easy to check, just pry off the cover and inspect the filament. If you need any replacement bulbs let me know the number on the base and I will see if we have any options. If the filament is intact then the only option would be to trace the wire back from each light with a circuit tester while the lights are on so you can find where the break occurs. I also recommend making sure each light that is not working has a sufficient ground.

Let me know once you have done the above and still need further troubleshooting advice.
