The invention relates to a lamp for a vehicle headlight with low-beam function, which lamp has an outer envelope and emits at least visible light of different colors from several regions of the outer envelope, characterized in that in that a partial coating is at least provided on the outer envelope such that, when the low-beam function is being realized, at least that region of the traffic space which lies above the bright-dark cut-off can be at least partly illuminated with visible colored light which is scattered at said partial coating, while at the same time that region of the traffic space which lies below the bright-dark cut-off can be illuminated with visible light of a different color in defined regions.

The invention relates to a halogen incandescent lamp for motor vehicles with an elongate bulb which is closed at one end and has a vacuumtight pinch seal at the other end, with at least one incandescent element arranged in the bulb, with a lamp cap connected to the pinch seal, and with current supply leads which are passed through the pinch seal to the incandescent element, with an annular optical filter which is provided at the closed end of the bulb. It is possible with such a halogen incandescent lamp in a simple manner both to change the subjective impression of the generated light and to improve the objective properties through emphasizing of a desired region of the spectrum.
