An exterior aircraft light includes a base plate and a plurality of lighting units arranged on the base plate, wherein each of the plurality of lighting units includes an elongated LED light source for emitting light, the elongated LED light source having a light emitting surface with a longitudinal extension and a transverse extension, with the longitudinal extension being greater than the transverse extension and with a projection of the longitudinal extension onto the base plate defining an orientation direction of the elongated LED light source, and a collimating optical system for collimating the light emitted by the elongated LED light source towards a main output direction, wherein the plurality of lighting units has at least a first lighting unit and a second lighting unit.

A light configured to be coupled to a surface, where the light includes a light source configured to emit light in three dimensions and a lens configured to direct a majority of the light emitted by the light source outwardly from the light source in directions along the surface. The light may be an anti collision light for an aircraft.

This beam shaper for an aircraft headlight comprises a light input surface (3) and a light output surface (6), the output surface comprises prism-shaped areas so as to deflect a light beam transmitted between the light input surface and output surface by guiding the beam in two directions (D1, D2) which are oblique relative to an optical axis (A) of the beam shaper.
