Need help replacing shifter bulb -- W124

[McLoffs]

The bulb illuminating the shifter on my 1993 300E is out, so I got to it tonight and can't figure out how the heck to get the bulb out of the holder. I found it, pulled the bulb out and futzed around trying to get it out of the holder but could not figure it out. Is there some sort of trick I'm not figuring out, or do I need to buy the whole thing as a replacement?

Thanks,
Mike
