Xenon/HID Bulb Replacement

[finestjammy]

Hi All

My 09 Cayman S (987.2 with the bendy xenons) will be approaching 7 years old in January. I thought I'd look at changing the xenon/hid bulbs before they go pop. I'm looking at the Osram Night Breaker Unlimited Xenarc. These are supposed to offer an improvement over the originals, not that they are exactly bad.

Quick question. I assume this is a bulb in bulb out operation? No need to level or use durametric to recognise/align them?

Links if anyone else is interested:
