Xlerad Bike Light
Smart bikelights are still novel to us, and Xlerad kicks the concept up a few notches. With no buttons or switches in sight, Xlerad turns on upon detecting movement, automatically and constantly adjusting brightness between 200 and 1000 lumens to accommodate your riding conditions. Other features include IPX-6 waterproofing to resist adverse weather, tap to switch between flash, fixed, and smart modes, and a quick release handlebar mount that fits all handlebar sizes.
