ive gone through 3 sets of h3 bulbs in the last year. i spent $50 on the first pair they lasted 4 months. yellow purple tint. second pair hyper blue $10. i know why they were $10. 2weeks and down goes the left bulb. 3rd pair hyper white $20 lasted 1 month. all looked great. went to autozone picked up some h3 for $7.99 when i first got the housing used them for 2 months then used the others. now im back to using the same bulbs. been using them for the past 2 months. they are still running but they look like a crappy flashlight bulb. was gonna try these bulbs but i dunno http://www.mytightride.com/43serplazxen.html
