The invention relates to a retrofit lamp (1) for a vehicle headlight. The retrofit lamp includes at least one semiconductor light source (410, 420), a plurality of light output coupling optical units (31, 32, 33), and a light-guide apparatus (2) which is embodied to guide light from the at least one semiconductor light source (410, 420) to the light output coupling optical units (31, 32, 33). The light-guide apparatus (2) includes at least one light-exit end (22), at which the light output coupling optical units (31, 32, 33) are arranged spaced apart from one another.
