Meet the OliLight: a smart wearable hiking light that can also get you out of trouble in the outdoors. The OliLight helps you see all around you. It has a sensor to detect unusual acceleration/deceleration to detect sudden movement and activate the SMS protocol.
You have 15 seconds to cancel your SOS message. If you are in trouble, a SOS message with your GPS location is sent from your smartphone to your contacts. The battery life lasts up to 10 hours depending on brightness level.
