Réjouissances du Peuple... In Reims on August 27, 1765

This is clearly electrical light. According to our given history, Sir Humphry Davy invented the first light bulb in 1809. This depiction is well before then and in another country.

Not to mention, this kind of electrical lighting depicted in this illustration would be considered highly advanced if it was in the late 1800's, but this is the mid-1700's.

Also worth mentioning that the first notably successful light bulb was made by Thomas Edison, which was revealed to the world in 1879, over a hundred years after this advanced electrical light depiction.
