vanity

I have a slight rattle that I have finally identified as coming from the passenger side lens or bulb on vanity light above the visor. It may be a loose bulb or housing may be bit loose. Can anyone tell me how remove the lens and get to the bulb? Any info would be appreciated.

Just bought my 2011 4.6 (tech pkg standard) Platinum Metallic with Cashmere interior night before last! (Nearly $5K under sticker OTD after much negotiation.) Been lurking this forum for about a week as part of my research -- Thanks to everyone for providing so much info here! Anyhow, after...

I've seen this plate in several pictures on the web... yet, I can't seem to locate any vendor that sells them. Anyone know where can I buy this vanity plate ?
