Stay safe and get more visible in traffic when riding a bike with Blinker Grips. They're easy to install and function as turn signals or side lights to keep you safe on the road. To activate the signal, all you have to do is press and release the button on the side of the handlebar where you want to turn and the LED light will blink for 15 seconds. You don't have to turn off the signal; it will turn off automatically. However, rules are rules, in most countries you are still required to use hand signals when making turns, even when using Blinker Grips. To use them as side marker lights, simply press the button for about three seconds.
