The one with the yellow center. I pull this **** and the yellow light in the center lights up, but that's all that happens.

I would guess fog lights, but I am making that up, with absolutely knowledge whatever.

I'm not really familiar with the B T5s but I heard many came with a switch for electric washers! Maybe that's the case...just a guess though!

Take care...

It is your fog light switch. Check them to see if they come on...if you don't have any, they are a nice touch, but very expensive if you put on the original Hella 128's. The switch is quite expensive as well so you are halfway there!

yep fog lights - but the lights were gone when I got my car,

Good originals are nearly impossible to find . Remanufactured ones are available but very expensive.

You should check to see if you have any loose wires up front that come live when you pull the switch and make sure they are insulated.
