Outer Limits 4x4 Board

Hi , I was just wondering if someone could help, I've got LED tail lights on my ute ,my problem is when I plug my trailer in, my tail lights stop working on the ute ,blinkers work, so do the stop lights and the rest of the parkers stay on as well its just the tail lights go off on the ute and every thing on the trailer works ,would puting LED's on the trailer stop this from happening or is there something else I can do.

Cheers Mick...

No that will not help, I would be checking the wiring on the plug for the trailer sounds like you are getting a back feed through the tail lights.
