The projection of H9 is stronger but after installing it I understood it was also a lot higher, blinding incoming drivers. So, I had to go to my friends shop that has the machine reading the hight of the beam and we adjusted it (there are adjusters behind the dash) to recommended hight. It has to be done with the rider sitting on the bike. That was on my first DL1000 2014. On this one, DL1000 2018, I knew it was going to be too high so before removing the old bulb, I parked the bike 5 meters away from the white wall and put some black tape on the line of the beam pattern on the wall. Then I mounted new LED bulb without moving the bike. This time, with the line on the wall, adjusting was simple as the dash was already off. It got perfect.
One more note, if you go with LED H9, mounting is a bit different then with normal bulb. LED bulb has the collar, just like the halogen bulb, but it is removable. In order to fix the bulb in its housing, you first separate the collar from the LED bulb, if I can remember well, by twisting it counter clockwise. Then you install just the collar the same way you'd install halogen bulb, close the spring and then twist the LED bulb in.
