Reebok CHECKLIGHT™ is a device that is worn on the head during sports and fitness activities with or without a helmet. It will indicate when the device has sustained an impact above a certain threshold. The device is made up of three parts: 1) an electronic unit, 2) a skullcap and 3) a power cord to recharge the battery. Reebok CHECKLIGHT™ uses LEDs to indicate various functions of the device. The Green blinking light indicates that the unit is on and functioning. A Yellow or Red blinking light indicates that the CHECKLIGHT™ device has received a moderate (yellow) or more severe (red) impact. An Amber (dark yellow) blinking light indicates that the battery needs to be recharged.
