D3060-TC Light System for Phantom 4 Pro lets you mount two D3060 anti-collision lights on all models of the DJI Phantom 4. The mount locks into the legs of the Phantom 4 providing a secure fit that ensures that lights will not fall off the drone mid-flight. Each D3060 light has 2 independent strobe capable LEDs that give 360° of light for visibility. Weighing only 2.2oz for both lights, your flight time will be minimally affected.
