And what about the sparkles? Here is the answer to all your questions. The Tower lights and beacon are lit up every evening from dusk until 11.45pm. As soon as it gets dark, the Eiffel Tower's golden lighting switches on automatically within less than 10 minutes, thanks to light-sensitive twilight sensors.
How much does it cost to run the lights at the Eiffel Tower?
The monument certainly keeps the meter whirring; each year it costs £963,600, or approximately $1.12 million. Each day, that's a bill of £2,640, or $3,074. All told, the tower has a total of 20,000 light bulbs lining the frame, and it takes about 22 megawatts of electricity per day to run.
