Abstract
A retrofit lamp (310) is provided. The retrofit lamp comprises a connector (311) for mounting the lamp at an automotive headlight; a body (312) extending from the connector along an axis (313); and a plurality of light emitting diodes (314) arranged at the body. The light emitting diodes are arranged along the axis and adapted to emit light (331, 332) laterally with respect to the axis. The retrofit lamp further comprises a reflective element (315) arranged at an end of the arrangement of light emitting diodes opposite to the connector. The reflective element is adapted to reflect some light (332) emitted by the light emitting diodes. Additionally—the extension of the arrangement of light emitting diodes along the axis is shorter than a light emitting area (114) of a reference replaceable headlight bulb (110), and—the reflective element (315) is configured to establish a virtual prolongation (340) of the arrangement of LEDs.
