If you want to take a look at a 500E take a drive over to Park Place Limited in Redmond. I believe they still have a 500E there for sale and you can pretend your considering purchase and pop the hood and do your inspection of the lights and fogs underneath.
I couldn't quite understand the different mounting arrangement you were talking about so if you want to post a picture (I'm a visual person) I might be able to answer you.
