Tail light works but brake light goes out

I have a 2000 WJ and the driver's brake light is puzzling me. The tail light works fine but when the brake pedal is pressed the light goes out instead of getting brighter. I've changed the bulb twice (#3157) and no luck. What the heck is going on here?

this happened to me too. took it to my mechanic and he had to redo some wiring to get it to work right. i think it had something to do with the trailer wiring harness we had installed

Ugh I was afraid this might be an electrical issue. No trailer hitch on mine though.

I had the same problem and it seems like the bulb wont stay in a certain position, if you can have another person hold the brake pedal down wiggle the bulb and twist it to see if it turns on...if it does just grab yourself some duct tape and make sure it holds.
good luck!

Here's what I did. I removed the brake housing and then the bulb. You will see three metal plates where the bulb connects to the housing. That housing that holds the bulb is plastic and it tends to fail. Mine got pushed down just enough to make a bad connection. Here's the good news for a fix...

Get a little flat head screw driver and gentley pry up on the metal plates. Get a small piece of folded paper and tuck it under the metals plates you just pryed up. That will make the metal plates stick up enough for a good connection to the bulb. I have had to do this twice and it's fixed. One time I actually needed a new housing causing the plastic that held the buld was cracked and there was no way to fix it.

Try that and see what happens.

this will work and its a common problem with the driver side one.
just make sure you put the socket in the right way or it will jam in their and be hard to remove

I've actually been having the same problem on my '00 TJ. What really sucks is that the mounting bolts within the housing are rusted really bad and I have had trouble getting them off. My sockets won't fit over the bolts (and I am using the right size ) and all other attempts with vice grips, pliers, etc. have been useless. Any suggestions here??? I'm pretty sure it is a connection problem for me too because I can feel some play in the wires coming from the relay inside the tub that attaches to the back of the bulb housing. Hopefully I can get this fixed up soon so I don't have to buy a whole new brake light assembly...

Thank you kwb18. I did exactly what suggested, prying and tucking paper in one step, and it worked the first time. Thanks a million.
