Traffic Warning Light / signal light

Traffic Warning Light

This kind of signal light on the road can remind the pedestrians to rush across the road when there's not enough time remaining, and can make the zebra stripes stand out to decelerate the running vehicles. The color of the warning light changes from green to orrange gradually according to the time remaining for pedestrians to cross the street. When there's little time remaining, the large majority of the zebra stripes would change into orange. This can remind the pedestrians to hurry across the road, as well as remind the cars that there are still people on the road,which greatly reduces the chance of car accidents.
