I just wanted to show off a little project I'm almost done completing on my Blazer. I ditched the dingy halogen bulbs (even after my relay mod made them better) for a pair of H4 conversion bulb/housings. These housings allow the use of a newer style 9003/H4 bulb where the bulb is replaceable and the housing/lens does not need to be replaced. The ones I got also have an integrated fog light within the housing that takes a separate H3 fog light bulb. I still need to wire the fog lights, but I did take the time to install the lenses and main bulbs this afternoon. One comment: These lights are 2 to 3 times brighter than halogens, but using an off the shelf bulb (9003 GE cool blue) it is still legal! Here are some pics: Here is the halogen on the pass side vs the H4 on the driver side on high beam. Here are both H4's installed on low beam: Finally, both H4's on High beam: The fog light portion of the housing reuired some modification to the headlight bucket and radiator support to fit. Alterations were made to both for fittment. Once I complete the fog light wiring this weekend I'll post up some more pics. This is a kick arse mod if you want to see in the dark!
