The bulbs in my fog light housing always wiggle around and eventually just stay off and crap - any way of fixing this? Or do I just need some new bulbs.

 

sounds like your "O" rings are shot...they should not wiggle and need to be water tight to prevent moisture and corrosion ...that's maybe why they don't work now.

 

so new bulbs it is?

 

Yep. that would be the best bet. I just changed the housings and bulbs on mine. You can get the housings for $14 apiece on Rock Auto. Its not a bank-breaking way to go if need be. Start with brand new bulbs and make sure you screw them in the right way. They should only fit one way in the housing.

 

One of mine did the same thing. First I just changed my bulbs, but it still did it, so I replaced the housing and It took care of it. I just bought a "like new" used complete fog light assembly with the because I also needed a new pig tail for only $15 for a wrecking yard.
