I have an 08-S80 - under the interior door handle there is a light or what appears to be a light that doesn't turn on. the dealer has not been able to tell me how to activate this and my sales person was not even aware of the light being there. This light is on every door handle. I'm starting to think that is like the emergency lights on a plane - it will only light up in the even of a fire or something like that. Help!! is driving me nuts.

I would try a diff dealer. A knowledgable dealer should know what it is.
