I assume the sooner the better because the Vision's I were using were great, but after getting a bad set that didn't last nearly as long as my two year old Vision's I looked around for something better. The pictures could do some good because I was actually stuck on a set of Raybrig H4h 702k/polarg h4h 702k. If there isn't much difference between those and stock then I may as well breakdown and get a set of oem H4h bulbs from opauto.
