Got my set in the mail Saturday and got them installed today. Not too difficult of a job for the DIY'er as the hardest part is installing the switch in the radio panel. (install tip) leave the lower cowl off till dark so you can adjust them. I found that if you put the bike on the center stand about 5 feet from your closed garage door the LED's cast a slight "rainbow line" effect straight across the door. This will allow you to simply adjust them up or down till the rainbow line is one line then you know that they are equal. If they are not the same you see two rainbow lines at different levels.
