Dunno, but I have not found anything short of HID that is superior to the PIAA bulbs. Neither has TireRack or IPD. <p>To hell with Consumer Reports and their we know what is right for you attitude. Anybody who will proclaim that all CD players sound alike and therefore they don't evaluate CD player sound quality clearly has an internal agenda.<p>Seriously, quality is the only bargain.
I would buy Osram SilverStars from <A HREF="http://www.powerbulbs.co.uk" TARGET="_blank">http://www.powerbulbs.co.uk</A>/<p>They are a European bulb which produces a better output than the US Phillips SilverStars. I use them in my car and while they are not HIDs, they are far superior than other bulbs I have tried.<br>
Dont waste your time and money on GE Nighthawks. I had them on my previous car and the difference was not THAT noticeable.<p>I suggest you go with PIAA. I have some friends who did have a bad batch(2 sets in one year, but thankfully, there is warranty). So far, so good for me. <p>
