Don't tarnish your favorite bike's sleek looks with some run-of-the-mill lighting—grab these solar-powered beauties instead. They've got modern looks, from the housing down to the bright LEDs and universal silicone straps, and modern tech, too, like four lighting modes and IPX4 water resistance. And if the sun doesn't look like it's gonna peek out any time soon, the lights can be juiced up quick with the included micro-USB cable.
