Red Light Green Light

How technology helps the parking lot.

The giant supermarket is more crowded than you can believe. All the time. So they've made it easier when you drive in - above each parking spot is a light. Green if it is empty and red if it is not. Hopefully you can tell in the photo. So, no creeping along - look up, find your spot, grab your trolley and join the queue for groceries......
