Even lower wattage LED light bulbs.

That is a fantastic exaggeration! Lol, I have heard of turbo Vw's getting 70 mpg, but I doubt even that. The Ex tried to buy a car on her own and brought home a 2010 (American obviously) Jetta with 6 speed manual turbo diesel - that car despite sitting in traffic got 47 miles to gallon, I measured it. Pretty amazing, and that extra 15 mpg's made up for the price of diesel fuel at the time.
It’s an ultralight 3 wheeler. Two seater, inline one Behind the other. Uses extensive aerodynamics. Seen it years ago when I was in Germany, it may have been Volkswagen that made it, it was a concept then. Not sure it ever made production. Kind of looked like an old drop tank on wheels
