The low beam bulbs have a good pattern and there is a well defined cut off point in front of the truck. I marked my old light patterns on the garage door before swapping in the LEDs and the pattern seemed about the same as far as cut off in height, but the LEDs do have a wider pattern that lights up the side of the road better. As far as I could tell they didn't need any aiming after the install but I did bump both sides down slightly when I saw how bright they were. So far no one has flashed their lights at me to indicate my lights are bothering them on low beam.
The high beams on the other hand aren't as great as the low beams. They really light the road up well but the light seems to be more diffused and scattered compared to the low beams. I think the reason for that is the plastic headlight lens over the low beam bulb has a horizontally ribbed diffuser built into the plastic that guides the light onto the road where the high beam has a clear plastic lens that lets the light scatter without guiding it down the road in a symmetrical pattern. When the lights are on high beams I sorta feel like the headlights need to be adjusted down some but my truck doesn't have a separate vertical adjustment for low and high beams. Both high and low beam bulbs are in a solid housing so they both move up and down together.
One thing I really noticed when driving with the LEDs is how much better they illuminate reflective road signs on low beams. Since the pattern is basically the same as before, it must be the color of the light that makes the road signs show up brighter. I'm very happy with the lights. I just hope other drivers on the road are to. ?
