Abstract

The invention relates to a method for operating a high-pressure discharge lamp (1) in a vehicle headlamp, wherein the electrical power of the high-pressure discharge lamp (1) during operation thereof is regulated at a constant level after the ignition and startup phase has ended. According to the invention, the electrical power of the high-pressure discharge lamp (1) is regulated at a first constant level for generating a first illumination application and at a different, second constant level for generating a second illumination application. The invention further relates to a device for carrying out the method.
