Abstract: The invention relates to an incandescent lamp with at least one incandescent coil which can be used for generating a high beam in a motor vehicle headlight, which lamp is additionally capable of performing the function of a daytime running light. The use of a dimmed high beam as an energy-saving daytime running light (DRL) has the disadvantage of a light distribution belonging to the high beam which is unsuitable for the function of a daytime running light. Furthermore, the high beam, if it is to fulfill the requirements as regards the maximum luminous intensity of the daytime running light, would have to be so strongly dimmed that the halogen cycle in the bulb of the incandescent lamp can no longer be maintained. This will lead to blackening at the bulb inside and a shorter lamp life.
