tail light problem


I'm having a problem that I can't track.

It's a std 2 wire setup. The brake lights work when the headlights are off (I checked and have 12v at the 1st wire on both sides), when the HL's are on the brake lights stop working and the tailights don't come on (I checked and have 12v at both wires on both sides). When I let off the brake with the HL's on the taillights still don't come on (I checked and now have 12v at the 2nd wire on both sides). So i'm uber confused cause according to the vt meter everything should be working??? I have tried multiple bulbs to make sure no internal bulb shorts.

Help?Huh??

Sounds like you have a bad ground some where.  I would start by checking the ground wires for the headlights and taillights.  Just don't look at them.  Remove the bolts at these grounds and clean any corrosion and/or rust you find.  Replace any corroded and/or rusted star washers you find at these ground locations.  Try this first.  Good luck.

I think i'm going to officially turn in my man card.

Sorry to trouble everyone - I have found out that self grounding sockets work much better when you install them into the tail lamp housings that they are supposed to ground out on (right here is where i'm banging my head on the desk repeating over & over, "stupid-stupid-stupid"). thanx for the quik responses - and i'm just going to go over here in the corner and be quiet now.
