T, be carefull about those "Blue" and any other high output no-name bulbs on ebay. They are sometimes China made goofy colored bulbs that are real junk. You have surely seen some cars around with weird looking headlights, that's what I'm talking about. I made that mistake ONCE, the description and picture was intriguing and the price was reasonable so I orderd a set. What came was a pair of bulbs in a very elaborate flashy packaging, totally in Chinese. I put them in my MINI and was too embarassed to leave them installed, took them right back out. I'm using the Sylvania top of the line brightstars (I think thats the name, anyway they are the best sylvania makes) in both cars and the bike now, I'm happy with them.
I'd like to read more about the PIAA's and maybe next time I have a burn out, give one a try against the Sylvania's, see if they are worth the price. Give them a side-by-side comparison.
