PIAA extreme white bulbs are the brightest bulbs I have tried, but that was for my 02 Ram. On my 07 I went with an actual HID kit from Maxvision and they are awesome. No lamp out light or flicker. (Just drove back home in the dark Wednesday night and got home @ 10:30 PM).

 

Well i got the Sylvania Ultras in the fog lamps and they are awesome. still havent heard when they will get the h13 in the ultras but waiting. for now i have 2 different colored lights. pretty tacky but i will deal until.
