By using a technology called magnetodynamic positioning (MDP), Osram Sylvania (www.osram.com) has designed a two-headlamp HID system (one light source and one headlamp on each side of the car for both low- and high-beam functions). MDP allows switching from low to high beam in an HID light source. By using a magnetic field, the stabilized arc can be captured, located, and moved from one position to another inside the light-generating capsule. This results in a straight horizontal arc on low beam. A high beam is produced by increasing the magnetic field to arch the arc toward the bottom of the capsule. The electric ballast allows for power modifications with daylight running lights at 22 W, low beam at 32 W, and high beam at 39 W.
