The lights on the top are the lows, the lights on the bottom are the highs. So what are the ones off to the side? If you pop the hood, there is a plug that goes into that area.

It doesn't look like theres a light in there...Is it just for looks?

I have an 03, without xenons. Mine looks a little different. (I pulled this photo from the web)

 

I'm guessing they're provisions for city lights. I forgot what the functions are but they're required on cars sold in Europe.

 

ummm im not sure, thats not the signals are they?

 

Not the signals, those are on the side and near the parking lights on the lower bumper.

 

Heres another view...

 

with xenons, thats not a bulb. its like a faux location that has 'Xenon Technology' written on one of the plastic slats that go horizontally across the bulge.

 

So theres no function other than decorative?

 

Without taking mine apart, they serve no function from what I can tell, but they may have something to do with adjusting/focusing the HIDs
