Sand Glass LED Traffic Light by Thanva Tivawong

Admin November 23, 2010 4

A sand glass traffic light concept for those no longer wanting to guess when the light will go green. An intuitive image-based system for indicating intersection safety, the stoplights provide a more visual and comprehensive display of when and how long lights will remain green, yellow, or red.

Safer? Well, that’s still to be determined. Designed by Thanva Tivawong, these sand glass traffic lights have quite the curb-appeal.

    take out the ‘ready’ step, as the yellow light always comes before a red light, but never a green one, therefore this would be way too confusing. It would be fine just going from a red light straight to a green, when the red ‘runs out of sand’
