It has been mentioned in the past that bulbs are available for replacement, but no part number or vendor source is stated. Does anyone have the direct answers?

I don't know the part numbers, but I had the dealer replace mine before I bought it and it he said it cost them around $250. Just to replace a stinking light that in one year has already burnt out again. This must be a common problem.

They sent it back somewhere.

All it is, is a little light bulb in there. You may be able to take the burnt one out and search around for a new one that matches.

If you get the job done, please give us a detailed description of how to do it. I need to change a burnt bulb as well, but don't want to attempt it without first knowing how.

not sure how the new radios are, but I took a 98 chevy radio apart and the lights are soldered in there.
