Trailer Light Fault, how to repair

Trailer light or caravan lights not working correctly, either dim or not coming on at all. In this video I install two pieces of electrically wizardry that fixes your problem.
The TEB7AS and the TEC3M electrical boxes of magic are installed in the back of the Land Rover Defender to fix the electrical issue with light not working as they should.

Please put grommets on the wires where your live feed goes through the battery box and bulkhead, movement can cause a bit of wear on the wire insulation and you will make the body live!
