Before the light bulb was invented in the late 1800s by Thomas Edison, people used candles, fire, oil lamps, or gas lamps or lights to create light while it was dark.

Gearges Bunnot, this man invented the candle that keep our houses light on a supposedly stormy night so our blackouts may be light by georges bunnots famous invention, the candle.
Nobody invented infra-red or infra-red lights as such. Infra-red is radiant heat and is a natural phenomenon and is emitted by essentially all light sources. Infra-red devices with no visible light emissions, are, in their simplest form, radiant heaters. What was invented were ways to use IR for night-vision - often called image intensifiers.
There wouldn't be light in the night sky back then bisides the moon

He invented the light bulb so we could have light at night!
Joseph Swan is not credited with inventing the first practical light bulb. That honor goes to Thomas Edison. The light bulb was invented to light the night.
Before people had invented artificial light it was so dark at night that well... If you couldn't see and you kept hearing noises in the night would you think it was a flesh-eating monster or a cute little bunny? -Artixthepaladin
they werent invented, they were just there. so they are out at night (i'm sure you've noticed) and they light up the sky, that all i can say.
