redundant controls

Has anyone attempted to replace the bulbs in the redundant controls on the steering wheel? I'm assuming they are bulbs. How do you remove the buttons? I have one burned out and figured I'd ask before I start digging at it. Thanks.

I worked at the dealer, we always replaced the buttons, but they were always warranty to. I don't think however that you can get them apart, if I remember right they are plastic welded, not snapped together.

How do they come out?

Just work around the edge with a small flat blade, or oring pick, they are just held in by tension, ie small hole, large piece, there are no clips etc, they just pull out, just got to get ahold of em.
