Stop hitting your head on awning arms! Attaches to most awning arms with a quick release Velcro strap. During daylight hours the fluorescent strap is hard to miss. At night turn on the 8 red LEDs to attract attention to the awning arm. LEDs are visible from the front and back side. Long battery life allows for over eighty hours of use. Use to warn of other obstructions such as mirrors, hitches or bike racks. Makes excellent campsite locator or marker. Batteries included.
