I installed LED's on my 2015 DL1000. Mainly becuase the H7 Low beam bulbs kept burning out. I installed a fanless LED bulb and once I got it adjusted properly it was pretty decent. That particular bulb separated into two parts. I then tried a different LED that had a fan (it was an update of the fanless bulb) and that worked properly no issues. The cutoff was quite sharp. No negtives I can think of. I added an H9 LED for the high beam and the expression "Let there be light!" cam to mind whenever I switched on the highs....
LED headlights are just not quite ready for prime time on a bike that gets ridden frequently at night.
