Thanks for responding Bluebird, "Reasonably" sure of a bad switch. I went through all of the different types of testing that I could do. Even went so far as to run a ground wire directly from the battery to the light sockets. No power to the rear at all. That was this morning. This afternoon I picked up the switch from O'Reilly and replaced it. The problem is now "almost" fixed. I have tail lights. I have stop lights. I have directional lights. I have 4 way flashers. The instrument panel indicators work. I say "almost", because when the light switch is on (either parking lights or full head lamps) both of the panel indicators are lit up. Any thoughts on this? Thanks, Cal
