Troubleshooting LED Trailer Lights on 5 x 8 Foot Tilt Trailer
Question:
If you used the Trailer Tail Light - 6-Function - LED - Submersible - 11 Diodes - Red Lens - Passenger # STL8RB then I recommend running a jump wire from the frame ground at the light to the mounting hardware on the unit. It sounds like the ground is not making a full contact, so the 12V battery is giving enough power to overcome the ground issue. I've attached a video of this particular light and the ground wire connection to the mounting hardware. The other possible issue is that some vehicles require a load resistor when using LED lights because the lights don't draw enough power for some vehicles to recognize connection. You may want to use Load Resistors or in some cases the Trailer Connector Adapter w/ Lamp-Out Sensor Bypass - 7-Way RV to 7-Way RV - Vehicle End # 20142 is enough resistance.
