I'm having a problem with my tail lights!

They are not working properlly when I turn on my fog lights and or my head lights.

If I do turn on any other running lights my tail lights get REALY dim to where you cant hardlly see them and I cant figure it out.
My center light is working good though but the cops don't care about that

Anyone have any ideas??

You have a bad ground wire somewhere.

Start with your main ground from the battery. Follow the wiring harness from the tail lights.
