The Hobie VisiCarbon Kayak Safety Flag Light Combo is a great way to stay safe on the water, especially at night. Battery powered light and reflective strips keep you visible in the dark while the hi-viz orange flag keeps you safe in the daylight hours. Lightweight, thin mast stays out of the way. Can be used on any kayak with drop in rod holders or an accessory rail. Flag doubles as a storage bag for the pole and light. 3AA batteries included power the 17 lumen LED.
