Abstract
Disclosed is a lamp, particularly for a vehicle headlight, comprising two spiral-wound filaments which are retained by three feeders within a bulb that is inserted into a base. The feeders are arranged on top of one another when the lamp is adequately oriented. A tail of the first spiral-wound filament is connected to a dimming cap, said tail being located at a distance from the base, while a tail of the second spiral-wound filament is connected to the central feeder, said tail being close to the base. The second filament tail that faces away and is located at a distance from the base is connected to the upper feeder. According to the invention, the lower feeder is connected to the dimming cap by means of an end, some sections of which are angled away from a longitudinal axis of the lamp.
