Later model 123 window switches are already LEDs.

I have a 240d so the climate control is different than yours. Mine takes 5 wedge base bulbs like the cluster, 3 behind the knobs and 2 behind the panel.

Spider also takes a wedge bulb, but you will need an LED that delivers light 360 degrees about the axis. That might be tough as I would imagine most of the wedge LEDs are set up to emit off the end.

I took apart my spider, cleaned both ends of the fibers with a q-tip dipped in alcohol, and also gently cleaned all the rocker switch faces the same way, after a fresh OE incandescent bulb it was like night and day.
