I ended replacing my light assemblies for aftermarket projectors (knock off's of the MORIMOTTO). My original lights were single bulbs (dual function: low & high beams) on right and left sides. The new assemblies are quad projectors. The light output and beam pattern on the low beam saw major improvement. The assemblies came regular H-1 halogen bulbs for both the high and low beams, but I did replace them with brighter bulbs from Autozone.
I wish I could figure a way to have all four projectors light up when on high beams. As it is now, only the high beam projectors or the low beam projectors will stay lit in their respective modes. If both were able to stay lit, the improvement to the light pattern would near perfect. The low beams really light up the area in front of the truck, but when switching to high beams, the distance is great but the area just in front of the truck loses the low beams and it is not so bright. My truck is a 2011 ST. I understand later models don't have this problem.
