Abstract
A system for light-based vehicle-device communication includes a computer programmed to generate a first light pattern based on a received identifier, actuate a vehicle light according to the first light pattern, and then identify, from received image data, a second light pattern emitted from outside of the vehicle. The system may further include a mobile computing device programmed to generate the second light pattern based on a received vehicle identifier, and actuate a mobile device light according to the second light pattern. The mobile computing device may be programmed to identify, from received image data, the first light pattern.
