They look interesting - but TUV hasn't approved them for any Porsche apparently: https://www.osram.de/am/night-breaker-led/index.jsp

They also don't appear to be available in the US. Amazon lists a Nightbreaker LED - but the cooling assembly/base is different from the one shown on the German Osram website. Of course, Osram-Sylvania also sells "Nightbreaker Laser" bulbs that are simply halogen bulbs with a blue coating on them. Apparently Sylvania-US/Osram's advertising department is somewhat lenient with the misuse of technical terms like "Laser"..

The German Osram site lists a number of retailers in Germany for them. I'll be seeing a friend this afternoon at a Porsche gathering, I'll have to see if he's heading to Germany any time soon...
