Abstract
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.
