With mine I bought clear corners that came with orange bulbs but I hated the way it looked next to the white headlights. I run sylvania superstar ultras as well so they are brighter than stock and it just makes it look worse. So I went down to Kragen and found some euro style bulbs in the tuner car section for the corners next to the headlights. The bulbs themselves are actually blue but they burn white and almost perfectly match the white color of the headlights. I think those two bulbs cost me around 3 or 4 bucks.
Then I also bought clear turn signal covers for the front and those also came with orange lights. However, living in California, they require you to have orange or red color for turn signals. So currently I'm just running clear lenses with orange bulbs behind them. Doesn't really look bad at all. However, I've seen the sylvania amber lenses that are grey coated or whatever(the same ones you were talking about that were $15) and I want to get some of those too. Just haven't got around to it. I think Kragen has them for like $9 a pair.
