The Knog Frog Strobe is a small yet powerful rear light, ideal for being seen on busy roads. The silicone body is compact and weatherproof and can be mounted in a variety of places on your bike, including on your bars, frame, pannier rack or on your luggage. With 4 flash modes, including the attention grabbing strobe setting, you'll make yourself nice and visible when negotiating traffic. With the additional purchase of a smoke machine, you could also throw a bangin' house party with a few of these strobing away!
