Spacecraft navigation lights

In 2011, ORBITEC developed the first Light-emitting diode (LED) lighting system for use around spacecraft. Currently, Cygnus spacecraft, which are unmanned transport vessels designed for cargo transport to the International Space Station, utilize a navigational lighting system consisting of five flashing high power LED lights.The Cygnus displays a flashing red light on the port side of the vessel, a flashing green on the starboard side of the vessel, two flashing white lights on the top and one flashing yellow on the bottom side of the fuselage.

The SpaceX Dragon and Dragon 2 spacecraft also feature a flashing strobe along with red and green lights.
