Can someone tell me how to access the sun visor/vanity mirror bulbs for replacement and what size I would need. I can't find anything online showing me any information. This would be for an 08 model if that makes any difference..... I just don't want to start pulling on something and end up breaking the dag on thing.

I opened up almost every light fixture in my CTT, however, that is one that I had not encountered. Given how thin the sun visor is, I am not sure the vanity mirror lighting is made to be "replaceable". This might be why you cannot find any information.

And I agree with you that is you try to just pull it apart, there is a good chance of just breaking it. Please proceed with caution.

Your local Porsche dealer parts department can give you a part number and get the needed part for you. They should be willing to email a blowup line drawing of it to you for no charge as well.
