For anyone interested, JC Whitney sells a wide selection of Xenon replacement bulbs that offer a much whiter light than stock bulbs and are much cheaper than PIAA's. I ordered a set for my 300ZXTT and could not believe the difference. Much whiter with no apparent loss of intensity like the "blue" bulbs you can buy for 3 times as much.

Just make sure you get the "Xenon" bulbs..... The site gives operational color comparisons between the different bulbs....

make sure the Wattage raiting is the same as stock or you will have problems with wires

alot of folks here have wires that are melting because of the higher wattage on head lights
