I ordered the Febi switches from AutohauzAZ about 4 years ago...they do (at least mine do) illuminate. About 10 bucks each.

If originality is not critical to you, I would look at a posting that I made on the "other" website some time ago, using W201 switches with a tiny wiring change. These switches are "double shot molded" with the legends built into the plastic itself, and not a polycarbonate label that will wear off. IMO, they also look better than the original switches. I built LED's into mine but this is not really needed.

If you don't want to change the wiring, the switch caps themselves are interchangeable so you can use an old cap on a new switch (there MAY be some subtle differences in how they are lit).

DO YOU BELIEVE the prices on the OEM MB switches?????????????????????????
