Flexible LEDs might still be some ways off before they become mainstream and are affordable enough, but here is a conceptual idea that might just make life safer on the road in the future. Imagine using flexible LEDs that are solar powered as traffic signals, being hooked (or pasted) onto trees and existing utility poles, making it a snap for both urban and rural installation. Of course, this would mean proper city planning and knowing where to plant those trees in strategic locations. Hopefully it won’t be too easy to vandalize either when the day comes that this becomes a staple in major cities worldwide.
