# Have any satellites had lights visible from Earth besides FITSat-1?

Clearly not a duplicate! of Why does the International Space Station have a downward facing light?

Starlink (and other satellites) categorically do not have exterior lights or illumination, that would be a waste of power for no particular benefit.

and that got me thinking. FITSat-1 was a 1U cubesat and had a bunch of LEDs on its exterior. It was programmed to blink Morse code and designed to be visible to people on the ground.

Question: Is this the only case of a satellite equipped with lights designed to be seen by people? I'm primarily asking about satellites that were built and ready to fly rather than plans or designs.

• No it does not answer my question, because I have asked "Have any satellites..." – uhoh Dec 22 '19 at 4:42
• @JacobKrall No it does not answer my question, because I have not asked about the ISS. Can you consider having another look and if you also determine that those answers do not answer my question, retracting your close vote? Thanks! – uhoh Dec 27 '19 at 5:43
• The ISS is a satellite by any reasonable definition. – Russell Borogove Dec 27 '19 at 6:02

• You would have if you were here a while back: five questions tagged humanitystar and one in Math SE, also here’s three about Mayak (Маяк) 1, 2, 3 and one about the Orbital Reflector. But here I've asked about lights rather than mirrors. – uhoh Dec 21 '19 at 3:35
