Got these on eBay and installed them over the weekend on the M3 and the MX. They seems to be the ones that RPMTesla wanted to release but didn't. They are going for $28 and seems to be from a US seller. One thing to note about this is that the housing opens up very easily - thru two or three installs and removals, the housing came apart but it is easily put back together. You may be tempted to glue it shut but you need it lose to rotate the orientation of the logo. I didn't bother with gluing even after orientation is perfect... Below are photos in low-ambient and dark lighting.
