VIFLY Strobe uses 5 3W Hi-intensity LED which provides the greatest range available for a mini strobe. 360º 3+ mile visibility satisfies all FAA guidelines, a must-have accessory for your safe flying at night. Each color has 3 modes, strobe, slow flash, and solid. You can use 3 white LEDs for the FAA 3-mile visibility request and a green/red LED for maintaining Line of sight (LOS). The strobe can remember your last setting of the mode, no need to set it again for the next time flight.
