replacing all interior lights with led - what bulb types?

I just replaced my cluster back lighting with 2 194 front facing SMD leds. Very impressed. Now want to replace the rest of the back lighting on the dash. I need to know what type of bulbs are used for climate control, fiber optic array, and shifter. Also if they need to be a non directional beam.The window switches I imagine are not replaceable and will play with them later.

As I am ordering these online I need to know ahead of time what types and how many. The MB numbers are no help. I searched and that was all I could find. Need the USA numbers. Thanks in advance.

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.

I did this in my SDL... the LEDs work great. I got the warm white ones, if I didn't tell you they were LEDs you'd never notice.
