Installed a set of PIAA Super Plasma GT (H4) bulbs this weekend. $75 from the tirerack.com. Install was a snap, just unplug the connnector, pull off the rubber cover, and the bulb is only held in with a clip. They give off a brilliant whie light, without being blinding. They are rated for the same power consumption as OEM (60/55w), but their light output os 135w/120w. PIAA products are always top quality, hence the price.......
