How do I fix a malfunctioning fog light?

Hey all,

I have a 2001 Sahara with OEM fog lights, of which the passenger side is "out." I bought a replacement bulb, but in the process of taking apart the housing for the 'burnt out' bulb, it ended up lighting up, making me wonder if there is a wiring issue. This lasted for a day before the light went out again.

Adjusting the the housing alone is not sufficient to turn the fog light back on, I need to unscrew the housing and make minor adjustments to the bulb itself.

So my question is: Do I need to re-wire the light? Or can I find another way to fix this bulb? Time is a bit of the factor, fog season is about to hit and these lights make a big difference.
I created a threat about a month ago where my side marker light would work intermittently, I spent hours tracing and testing wires. Everything tested good. In the end I sprayed a bunch of electrical contact cleaner from the auto parts store in the socket, let it dry and it has worked perfectly ever since. Moral of the story: try the easy shit first.
Replace the stock candle powered fog lights with LED's and never look back. I tried to sell my oem lights for $20 and ended up throwing them in the trash.
