WELL, Got them in .. The alignment was pretty easy... Thanks for the info on that.
I'm not really sure how much I like them.. Very White... Almost too much reflection
from the road with the dims on.. The brights seem kinda high..
I did adjust the housings just a bit upwards to try and reduce the glare from the
road right in front of the Yukon.
I'll have to drive a bit and decide if I want to go back to the regular H13/9008
bulbs
Yes, make sure that the headlight housings are adjusted to the correct height. The conversion to LEDs alone should not materially change the housing height adjustment, but perhaps, the housing height adjustment was not correct to begin with. Measure the height from the ground to the center of the LED popsicle stick. Then, on level ground measure out 25 ft. from the front of the truck, and measure the top of the light beam on the low beam setting, and adjust to the top of the light beam is at the same height at the height measure at the front of the truck. You can also drop the height of the top of the light beam as much as 1 inch down at the 25 ft. mark, if you want.
And, yes, if properly adjusted, the high beam light pattern will be significantly higher than the low beam light pattern.
