BlinkerGrips are ergonomic bicycle grips that come with integrated battery-powered LEDs that function as side marker lights and turn indicator lights. You may think it’s dorky to have handlebar grips with glowing lights, but it actually looks pretty cool in the dark. Not to mention the fact that it’s a safety issue and you need side markers and turn indicators to prevent being plowed down by a motorist in a hurry. The ergonomic grip comes with an adjustable wrist rest that you can set to match your thumbs and give you maximum comfort. It is completely impervious to hard knocks and the inevitable crash or two. It’s also splash-proof and has a lock-on system. The energy-saving feature allows for up to 2,500 turns on the set of four AA batteries that come with the BlinkerGrips.
