Solar Light Cap

The Hat that's a Solar Charger
Looks like the ubiquitous baseball cap has had a solar makeover. UK company Solar Select has come up with a hat that has a solar panel on the top part of the brim and LED lights on the under side. Result? After a full day hiking you’ll have enough light stored to carry on for half the night.
The initial charge takes three days (!) after which the hat takes eight hours to fully recharge. Each full solar charge will knock out five hours of light. The light can shine from 6 feet / 1.8 meters up to 30 feet / 9 meters ahead of you, depending on the jauntiness of your cap angle.
The manufacturer notes the product is “hands free” – which is definitely something most people look for in a hat.
