Trailer Lights

I am having a problem with my trailer lights.
The brake lights and turn signal work fine, but the running lights do not.
Any suggestions??
Thanks

That's on the same fuse as your dash lights. They probably don't work either.
Check your fuse.
You also have one wire just for that.

And it's Brown.

Both my HD's have a seperate fuse in the under hood fuse box for all the circuits on the trailer lights. Kind of wild when everything on the truck works but there are no running lights. That took a little while to figure out. :( :D

Drive during the day. :D

Make sure you got power coming out of your truck at the light plug. If not, check your fuses like the others have mentioned. If you have power you are going to have to trace the tail/marker (usually brown) wire on your trailer and see if it is cut or grounding out on the frame somewhere.
Electrical problems on a trailer can be a real pain in the ass to track down sometimes. Good luck.

if all the others sre not it check your ground could cause strange problems :hammerhea

Thanks for the suggestions, I will check the fuses, but the dashboard lights are still working (2004 chevy tahoe) and I will trace the brown wire.

Did ya start with the most obvious like a corroded connection at the plug or burned out lights..... put power to the connector on the trailer and see if they light up, then you can rule the trailer out as being faulty..
