I just got these bulbs for my new cavy.

Claim: Extreme cool blue light, 4000Kelvins, like a 120/110W bulb.


Cost: $90 or so, depending on application.

Install: Easy.

Results: minimal difference, almost not even noticible. However, my cavy uses a 9007 light bulb, there may be a more drastic difference with an H4 or something.

Agreed. Sylvania Cool Blues look exactly the same.......and work just as good, if not better than PIAAs. I had a friend with PIAAs in his Civic.....one burnt out....so he replaced it with a Cool Blue......coulnd't tell a bit of difference. Plus the Cool Blues are only like $30 a set.

 

I had the PIAA's for about 2-3 months before one blew out. I also had a set of gold Hella bulbs in my fog lights for about a month before one exploded and permanently turned one of my fog lights yellow inside. Lesson learned: stick with factory bulbs unless you go for the real deal...HID.

 

Agreed...

I guess I should have done a little more research first, but it was one of those spur of the moment purchases.

 

I initially had a set of no-name hyperwhites.... those blew within a few months... then I got the PIAA Superwhites those worked fine for nearly a year before the driver side one blew out. Moral of the story? Either stick with the stockers or go full blown HID if it matters that much to you. Personally, I have a hard time justifying $400+ for headlights.

 

I'm not entirely sure, so I won't make any glaring accusations, but umm.. have ANY of you upgraded your wiring harnesses before using the PIAA (or any other bulbs like that) ?

I blew out 3 sets of Silvania's kept taking them back getting replaced, and finally I got sick of it and bought PIAA's, and noticed that the Silvania's had melted my wiring harness somewhat. With some research I found that most if not all Hal / Xenon lights require a better wiring harness than most cars stock.

8 months ago I put in my new wiring harness made for HID-equipped cars, and the PIAA ultra whites, and have not had one problem.

Moral of the story: Before you call a great product crap, do a little research.
