Amazon, in its quest for greater efficiency, has developed new systems to shave seconds off each package delivery and to help customers make faster buying choices, even for new product types that they may know little about.

Amazon announced on Wednesday it had created spotlights within its trucks to guide delivery people to packages for each stop along a route.

The technology, which Amazon is calling Vision Assisted Package Retrieval, works by shining a green light on packages so that the deliverer does not have to waste precious seconds reading labels.
