A versatile accessory, the bright XLC CL-E15 flashing light is
capable of functioning as a normal rear light as well as an indicator
(also known as a turning signal or blinker). Remotely controlled, the
light flashes to indicate a left or right turn. Alternatively, it can be
left as a steady rear light or flash intermittently. Containing a
rechargeable lithium-polymer battery of 3.7V/800mAh with overcharge and
over-discharge detection and a micro USB charging cable, the XLC CL-E15
flashing light is a convenient choice. With a handy display to indicate a
low battery, you’ll never be caught with a dead battery again.The
remote control has an included battery and can be fixed to the handlebar
for ease of use.
