Abstract
The invention relates to a halogen bulb comprising two filaments that are located (21, 22) in a lamp body (10), a first filament (21) being designed for operation at a higher electrical output than the second filament (22). The filaments (21, 22) are designed in such a way that the second filament (22) generates a lower luminance than the first filament (21). The first filament is preferably used as a main beam filament and the second filament is used to generate a daylight driving beam.
