A couple of weeks ago I posted a question about the transmission selector lamp and where to get it for my 300D. Most of the replies were that it was driven off the "spider" or it was just a regular dash lamp, but it isn't. I finally found what it is. It is the same lamp as the ashtray light. 3898 2W.

Hope this helps someone in the future.
