OK, I found 289 threads on "PIAA" and all the comments.

Anyone found a superior headlight/foglight/all-around lighting that is notciably superior to the factory Tungsten Halogen headlights/foglights? Non-HID.

I have some options here not available to you guys in the states. I also searched the PIAA website and tirerack and it looks like only the 9004/5/6 are available stateside. Several other PIAA lights available here besides X-Treme White. I can also get Catz HB3/HB4 and Rayburg along with Phillips if I look hard.

I recently switched to the Catz map lights and dome lights and they are pretty sweet. Any one else tried Catz?

So what's the consensus on what is really better than the factory lights for a 4th gen?

TIA,

 

The Philips Vison Plus is supposed to be the heat, but they don't make it for the 900x lamps.
Philips does make the Premium which is supposed to be 30% brighter... I run them and there was zero difference (side by side) between them and the factory lamps.
