ultra bright 9 LED Bike Taillight

This is one flasher that's going to get noticed! Unique polycarbonate lens has special 'focus spots' that magnify the intensity of the super-bright LED. Plus, tiny refractive dots molded inside the lens create extra sparkle to increase your visibility from angle. Attaches in seconds to bike handlebars or seat post - mount included - and when you're done with your ride, push the release lever to remove. Use the built-in belt/pocket clip and you'll have high-visibility walking, running or other activities. Seven light settings include constant on, slow/fast flash, slow/fast side-to-side running and strobe. Dimensions: 3"W x 1-1/2"H x 1"D (without bike mount); weight just 2.2 oz with 2 AAA batteries (not included).
