well, according to jtivat, the Porsche light is much like the E series and uses an MN type lamp assembly [reference: link]
Don [Mcgizmo] referred to it also as SureFire Porsche E series and installed a LED in it. notice the custom LED assembly is much like the shape of the MN02-MN03. [reference: link]
I'm not sure where the "LED" part came in, but if it is, gathering from the date its most likely a luxIII or luxV
