No problem. The bulb is one setting, which is ON. Actually that would be two settings, ON and OFF. It's basically always on high beam, but the shield inside the projector blocks the light from directing upwards into drivers eyes. When you engage the high beam switch, it sends 12v to the solenoid inside the projector, and the shutter flips down, directing light in all directions, causing a 'high beam'. I hope that helps.
