WingLights

Bike etiquette has it that signalling your turn involves holding out your arm, temporarily sacrificing balance in the hopes of being noticed. Unfortunately, this doesn’t work as well as we’d like to think, particularly in poor light and weather conditions. WingLights, instead, brings the tried and true method employed by every other road vehicle to your bike. Replace your handlebar covers with their magnetic fittings, then stick WingLights onto your handles before riding. One quick tap activates the desired signal, emitting highly visible amber light via LEDs, and another deactivates it after the turn is complete. They’re also designed to be waterproof and shockproof, last 3 months on a single set of batteries, and pop off your bike in an instant to prevent theft, attaching magnetically to the included carry-away keyring.
