Blackburn's insanely minimalist CLICK front lights are incredibly visible to drivers, yet nearly invisible on your bike. A simple 'click' of the lens will power up 2 LEDs that pump out bright light that is even visible from the side of your bike for cross traffic. The slicone mounting strap makes it easy to install/remove and works on pretty much any handlebar or bike frame. Two CR2032 coin cell batteries are included and are super easy to replace.
