If some of the Optronics LED Trailer Clearance Lights # MCL32ABB that you recently installed aren't powering on I recommend checking the white ground wires on the affected assemblies. Make sure the wire is securely attached to a clean, bare metal surface that's free of any debris, paint, or corrosion. You might want to sand down this surface before re-attaching the wire just to be sure.

If this does not resolve the issue I recommend removing the assembly from the trailer and applying 12V power directly to the light (still making sure the white wire is grounded). If the light still doesn't work then there is likely an internal issue and it will need to be replaced. If this is the case please just let us know as the LEDs do come with a lifetime warranty.
