Lightdrops, by designer Sang Kyun Park, are umbrellas that illuminate when raindrops trigger the light emitting diodes (LEDs) within their frames.
Clothing and shoes that glow in the dark as well as bike reflectors help reduce accidents when walking, jogging, or bike-riding in low-light conditions. Lightdrops umbrellas have the ability to aid in this area as well: because they illuminate, they can help make their users more visible to motorists and lessen the likelihood of an accident.
Implications - Say goodbye to grandma's umbrella, because LightDrops is the new wave in rain protection. The potential energy from the raindrops transforms into electrical energy which powers the embedded LEDs and lights up the umbrella so owners can forget blending into the nighttime. As the rain gets heavier, the light gets brighter, ensuring no one loses their way in a storm.
