Had to do some research to replace a brake light on my E92 (pre-LCI) and "W16W" as you all probably know is something that you can't go into the parts store and ask for... put together a list of Sylvania part numbers that you can actually buy in the US... hope this is helpful. I just did the exterior lights but will flesh this out if I need to replace any of the interior ones.

Damn German cars... seems like every time I get a new one I have to do this whenever I need to replace a bulb
As per usual the Sylvania catalog at the parts store wasn't completely accurate...
