Abstract
It is provided a lamp (12) for an automotive headlamp (10), comprising a filament coil (14) for emitting light (22) and a nominal alignment axis (32) for aligning the filament coil (14) such, that the filament coil (14) is positioned in the middle of an allowable tolerance box wherein the filament coil (14) is arranged shifted to the nominal alignment axis (32). Due to the shifted arrangement of the filament coil (14) the flexibility given by the allowable tolerance may be used for positioning the filament coil (14) such, that the projected image (18) of the filament coil (14) is projected nearer to the bright/dark-cutoff (40) without blinding oncoming traffic.
