Does anyone know how to remove the headlight lense cover on a 2006 XK8? Seems like there are 2 snap connectors on the top.

 

This thread should help you remove the headlight assembly:

Once it is out, gently pry up the tabs separating the lens housing and the body of the headlight (I think there are 2 or 3 on each long side and one on each end). The lens and the housing will then separate, it will be helped automatically by the rubber gasket pressure. Replace the lens with the new gasket it comes with.
