Through the wonder of the interwebz I've been reading about using 9011 HIR and 9012 HIR bulbs in place of 9005 and 9006 bulbs in my Astro's headlights. Has anyone here actually done this? Is it worthwhile compared to just using some premium 9005/9006 bulbs ? Or should I just mount a couple of KC Hilites on the bumper and be done with it ?
