The 4 Foot Kayak Safety Flag with LED Light allows you to be seen while out on the water. The 4 Foot Kayak Safety Flag with LED Light will help other boaters see you in low light conditions, backwater areas littered with tall grass and even in larger swells. The included white LED light is simply turned on by twisting the bulb at the top of the flag pole and 5 different settings. To change the setting, just turn the light on by twisting the bulb clockwise and then turning it off by turning counter-clockwise. Quickly turn the bulb back on again and you will be on the next setting. Repeat this process to select the ideal lighting option of your choice. If you have internal access to your boat through a hatch, you do not need any additional mounting accessories. If you do not have access to the interior of your boat, you will need the deluxe mount bracket, sold separately.
