Make sure you have a good trailer to truck ground. Check the white wire on the trailer harness and make sure you have a good clean contact at the trailer ball. This is a ground source between the two.

Why are trailer LED running lights too bright? 2005 Jeep/2007 Harley. FIXED!! :)


brake lamps and parks are swapped
brakes are the high current lamps and much brighter.
you have them backwards.
AH ! LED lamps
and you really mean
the brake are too dim,,and parks are too bright.
and what is it not.?
it's not the jeep putting out too much voltage to TAILS. sorry its 13.3v to 15v running, on all cars.

what is it.?
well the lamps for tails/blinks are low power LED lamps. (like there relic cousins)
and brakes are higher intensity LED lamps (by LAW)
same with incandescent, (LED dont change DOT laws on candle power, sorry)

92 Jeep Cherokee trailer running lights wont work


there are 2 systems. you mixed them, (bad_)
that takes a special adapter.
if in USA, ask the Uhaul shop for where to get the correct adapter.

your trailer is wired, old fashion, with separated wire to each function.
the car is not. (wired like 60 chevy)

option 2, is go to jeep and get the trailer kit. bingo.

option 3.?

How do I get at the wiring to tie in a trailer


All the wiring you need is there in the trunk, and the harness plug you buy will have quick connectors to splice each lead.
So all you have to do is to run the wires out of the trunk.
You can drill a hole, but most people just loosen the bottom of a light lense, and stick it throught there.
The rubber usually is flexible enough to allow this.
But don't do it at the top, because then water could get in.

Trying to hook up trailer lights


taillights on what? Everything - needs to be grounded is the FIRST thing to remember. Try etrailers.com for parts or tech assistance or Google "Hoppy" trailer light kits.

2006 HHR trailer wiring?


Check ground wire to the trailer. On the vehicle and the trailer. Make sure you have a good ground as lighting will seek any path for ground which will feedback and cause lights to act really weird.

Driver side park lamps not working


check fuse # 2 in the relay box up front and look for a "park lamp relay control" in the control module.
