When you think of walking the Las Vegas Strip at night, you can’t help but think of neon, LED, and incandescent lights. They all help bring energy and life to the night. The International Space Station images show Las Vegas as the world’s brightest city.

According to research from Smart Lighting Industries, a firm based in the United Kingdom, the Las Vegas Strip, with over 12,000,000 lights, is the most expensive tourist attraction in the world to light. The light bill on the Strip is about $443,521,846 annually. It all starts when you enter the Strip. One interesting, fun fact is that the 4.2-mile Las Vegas Strip is outside the city limits.
