A helicopter search light (2) comprises a housing (6) with a mounting portion (4), which is configured to be mounted to a helicopter (1), a light source support (8) arranged within the housing (6) and at least one optical system (15). Each optical system (15) includes a group (10) of at least two light sources (10a, 10b, 10c) with different light emission characteristics, which are arranged on the light source support (8); and a reflector (12), which is movable between at least two discrete positions, each position being associated with one of the at least two light sources (10a, 10b, 10c), with the reflector (12) in each position only reflecting light emitted by the associated light source (10a, 10b, 10c).
