Got these new courtesy lights on the MX and my M3. These look like the ones that RPMTesla was going to release but never did. They are going for $28 on eBay (and seems to be shipping from US; got it in a week). Pictures below; one is in low-ambient light, one in the dark. One thing to note about this is that the housing the on the light is a bit poorly design for my taste. The lens comes off after a few installs and removals but you can put it back together.... You will be tempted to glue it shut but glue will prevent you from rotating the lens if it is not oriented the way you want.
