Tail light keeps burning out

The driver's side tail light/brake light keeps burning out on my 2005 KJ. I'll fit a new bulb and get maybe a week out of it before it blows again.

There are obvious signs of overheating on the bulb holder, so is there anything I can do to fix the problem permanently? Do I just need a new holder?

You probably need a new socket. Once it goes bad it burns bulbs out fast.

The little metal fingers where the bulb holder contacts in the actual tail light housing likes to melt and sink into the housing.The only real fix is to get a new tail light housing and new bulb holders(do not come with tail light housing).

I've discovered what the problem was. There's a known issue with a clear plastic surround inside the tail light housing being affected by heat over time. Eventually it breaks away and touches the bulb, creating a hotspot that quickly burns it out. I took the unit right off the Jeep and gave it a shake and what do you know, that's what had happened to mine. It's a hefty chunk of plastic rattling around inside the tail light, but it's invisible from the outside.

Officially the only fix is to replace the entire tail light housing, but unofficially you can get some needlenose pliers in there to break up the plastic and pull it out (it's toughened, so it was a real PITA). Even though the plastic is supposedly some kind of lens, there's no appreciable difference to the brightness of the light compared to the passenger side once you've pulled it out. Hopefully my problem has now gone away.

Same problem. I took a small wood screw (brass). Drilled a hole from the outside and pulled the clear plastic up to the outside cover. Problem solved.
