It is provided a lamp, particularly halogen lamp, for a headlight of a motor vehicle, comprising a light source () for emitting mainly white light, a mainly transparent envelope () encapsulating the light source () and a filter element () provided at the envelope (), wherein the filter element () is adapted for deflecting visible light of a predefined wavelength interval such, that mainly blue light can be provided above a bright/dark-cutoff (). Since the deflected bluish light is above the bright/dark-cutoff () an oncoming driver recognizes earlier the light. At the same time the oncoming driver is not blinded by the blue light above the bright/dark-cutoff (), since not the whole emitted light () but only a smaller wavelength interval is directed above the bright/dark-cutoff ().
