Abstract

The invention relates to a lighting system for a motor vehicle, to provide three lighting functions in which the color temperature is the same, comprising a projector headlamp in which is arranged a high-pressure discharge lamp which is connected to at least one ballast, wherein precisely one high-pressure discharge lamp (1) is provided and the projector headlamp has two masks (4, 5) which can be moved into the beam path of the said projector headlamp.
