Those are pretty slick, but they are kind of ugly to look at in the day time! I'd be interested in someone posting a pic of these lights on a car especially with a crystal clear lens like we have on the 3!check these out. they are a white marker until the turn signal is started. then they flash amber. once the turn signal shuts off, they go back to white.

Edit: I just checked some of my pics and noticed the 3i looks like it has a piece of amber plastic over the turn signal! I would think this would need to be removed and have a clear lens added in order to get rid of the amber look completely. I think 3s models or may just the GT already has this amber plastic missing. Could be common knowledge, but just thought I would add it anyway!
