Abstract
A lamp 10 is described which may be used in an automotive headlight 12. The lamp 10 comprises at least one filament 20 within a transparent lamp vessel 16. A color filter portion 30 is provided through which light is emitted with a color change. The lamp vessel 16 further comprises a color transparent portion, through which light is emitted without a color change. The color transparent portion is arranged such that an illumination beam of light 40 is emitted through the color transparent portion to achieve a non-colored illumination. The color filter portion 30 is arranged such that only peripheral and/or scattered portions of light are emitted through the color filter portion to achieve a color appearance of the headlight 12 in operation of the lamp 10.
