What is the best (brightest, and longest sight distance) brand replacement for the H11 low beams on our FiST? I currently trying out some Sylvania Ultras, but not greatly impressed, not sure if I am truly seeing much of a difference? I have seen some decent prices on PIAA bulbs online. Are the PIAA worth the extra cost? Ans what about those Sylvania ZXE bulbs? Are they good? Or just for the blue ricer look?
