You know what I did? I just took the bottom bolts out, and never have to worry about those again. XD Personally I just love the focus. Gas mileage can be better though. The ultra's are pretty good! Very noticeable difference in the color out put, but to me it seems like I lost a few lumens due to the blue tint. I'd rather to lose a few lumens to have a whiter light than to have the ugly yellow ones.
Complete, and full retrofit coming soon!
