A sighting device for small arms comprises a holder 1 which near its one end carries a light transmitting mirror 7 and at its other end - in the focus of said mirror - a first light source 14 and a second light source 16, both sources being mounted in front of adjacent faces on a cube beam splitter 11 in such a way that light from both sources 14, 16 coaxially, will follow a common path, the said light sources 14, 16 being included in circuits which are alternatively activated. The light sources may be LED's, and emit different colours. Optional apertures 15, 17 may have different sizes and/or shapes. <IMAGE>
