Abstract
This invention relates to aircraft light units, in particular aircraft light units used when landing and taxiing an aircraft. The invention provides an aircraft light unit comprising a first light source with a principal beam axis in a first direction and a second light source with a principal beam axis in a second direction, the second direction being different from the first direction. The first and second light sources are arranged such that they can combine to create a net light beam in a plurality of different directions by variation of the power supplied to the light sources.
