Okay guys, here's one for you.

My passenger side, rear tail light is having issues. The light that turns on when I turn on all my lights is having problems. The bulb is fine, the wires are not. It if the wires aren't PUSHED into the bulb holder, it turns off. I have tape putting pressure on the wires so it doesn't shut off, but it's really annoying because sometimes it gets a little loose and the light turns off.

So in closing, wires that go into the bulb holder are having problems. Not bulb. HELP!

 

You might kick me for this, but I had this exact problem when putting in my "new" tails. What I did was I kind of crunched the wires together and put a twisty tie around them to keep them together. The way I crunched them together kept the light on. No problems since.

 

*KICK*

But I might do that lol. They're stock tails, but I have had other tails in before; but that was a long time ago.

This JUST started happening, so we'll see what happens.

 

I would start with going to radio shack (or the equivilant) and getting some contact cleaner and making sure all your connections are clean and shiney.

If that does not do the trick, you might have to do some rewiring. I know one of my fogs, the lead wire is corroded all the way up the insulation.. but using contact cleaner helped a lot.
