Space-based solar power (SBSP) is the concept of collecting solar power in outer space and distributing it to Earth.Potential advantages of collecting solar energy in space include a higher collection rate and a longer collection period due to the lack of a diffusing atmosphere, and the possibility of placing a solar collector in an orbiting location where there is no night.

For decades beacons have used as an enhancement or warning for busy crossings and heavy traffic areas. Recent LED improvement, new regulations for 12″ lenses, and solar power have made this timeless device even more effective and more versatile. This LED dual beacon incorporates these
