Part of the allure, or conversely the deterrence, of riding in the city at night is the excitement of the unforeseen, be it a pothole, a pedestrian, or a car pulling out from a side lot. Needless to say, part of being safe is being seen. If you like to ride in town at night, maybe a small head light would be a wise addition to your bike. The Knog Frog Strobe White LED Light is super lightweight, weighing less than a GU packet, and it is unobtrusive in the way that its flexible silicone body clings securely to a stem, handlebar, pack strap, or through the vents in a helmet. With its undisputable convenience and power to make you visible to inattentive drivers up to 600 meters away, wouldn"t it be silly to not have one?The Knog Frog Strobe White LED Light features a super bright LED strobe system with a built-in lens. It has a burn time of 50 hours on steady beam and 80 hours when flashing. It can be used as a constant light and there are three flash modes -- fast, faster, and random. The Frog Strobe is available in five body colors -- Black, Red, Transparent, White, and Lime. 19 grams.
