Designer Sang-Kyun Park has come out with the LightDrops. Using white umbrella at night does give awareness to driver but with light it will be even better, more visible in the dark. How is it powered? “As the water pours over the surface, potential energy from raindrops slamming onto the conductive membrane called PDVF transforms into electrical energy powering embedded LEDs.” Meaning to say the heavier the rain the brighter the light, so pray for heavy rain. More pictures after the break.
