Your Demco Kar Kaddy SS Tow Dolly with Disc Brakes # DM9713045 with one light not working has some basic troubleshooting we can do. The light is not incandescent but rather LED so there isn't a bulb to check. You will want to check the wiring connections. I recommend starting with the connection point to the vehicle. Make sure the pins are working correctly on your vehicle using a circuit tester like # PTW2992. Then clean the connections on the vehicle and trailer using a little sand paper. Connect the trailer wiring and next check the ground wire connection. It needs to be bare metal to metal and free of corrosion or debris. Next check the connections at the tail light. Make sure the connections are solid and clean them up too. If that doesn't solve your problem you may need to replace the LED itself. If you take a photo of the back of the light itself and let me know the diameter we can get you an LED replacement light if all the electrical is functioning correctly. We also have the Replacement Fender Lighting Repair Kit for Demco KarKaddy SS Tow Dolly # DM67VR to replace the trailer wiring as well as the light.
