^^ They give the car the biggest difference. I couldn't stand having my headlights pop up so freakin' high. It was just ugly at night when going down the road, that's my opinion though. Here's a couple pics of mine when they were installed but w/o the shroud. I just never got around to doing so and the car has been sold since then too.
