The Mako(TM) line offers four models and up to 250 lumens, not only allowing the cyclist to be seen, but allowing the cyclist to see as well. Our favorite feature is the side "gills" that emits light, it not only looks cool, but makes the Makos more visible. The Mako(TM) line is easy on the wallet and easy to operate.
