Alright guys, I am awaiting the arrival of my 22B from Japan and am trying to look for ways to put a foglight in one of the rear clusters, did it to my MR2 last time and was a piece of pi55 but wanted to check on here before I go searching...

Any help appreciated!

Cheers,
Chris

 

I've managed to do this on my STi - where the fog light is fitted on a UK car. I bought the parts and made up a bulb holder for a standard 21W rear bulb, although you can probably source a factory one.
After taking the cluster from the car, I carefully made a hole in the inside of the light (using a soldering iron to melt the plastic and avoid filling the light with bits). They're silver inside which also made the job simpler.
Once its all fitted together re-install the light in the car and seal it well as they're prone to leaking. Gutter sealant works a treat.

Cost all in: Less than £5. But still need a factory fog switch.

I stupidly didn't take any pictures of the parts, but heres the finished job:

 

or use the reversing light like my wrx has had this done

 

Got my car with one of the reverse lights changed to the fog light and who ever did it put a red film neatly over it you can hardly notice its stuck on the outside of the lense
