Sitting on the bike, the lower left adjuster will raise/lower the beam, the top right adjuster will tilt the beam left/right Make sure you adjust the beam while your sitting on the bike as it will raise up with your body weight. I've adjusted mine so it peaks at around 30 meters and added an Osram night breaker H4. The lower beam is now perfect for nights/days, sit's on car number plates at around 20 meters, but the high beam is slightly bit high but more than good enough.
