The Entity RL100 Rear Light is your safety beacon to warn any distracted drivers or road users of your presence by blasting a near blinding 100 lumens of bright red light from the 50 chip COB LED. All that power is neatly packed into a slim compact design that will make you forget you even have it on your bike. The 180 degree light beam is ideal in a city scenario where traffic might come at you from any direction. The clever strap mount also allows you to choose between a vertical or horizontal layout for the light, to make it more streamline with with seatpost or to make it visible over pannier bags you might be carrying. IPX4 Waterproof rating, USB recharging and included saddle bag clip complete the list of features of the Entity RL100, a light you can rely on to have your back.
