This Monkey Light 8-Bit Bike Wheel Light from ThinkGeek will turn riding excursions into light shows through the use of 5 super-bright LEDs on each side of your tire. A battery pack straps to the bike’s wheel hub while the light unit quickly installs near the tire, beaming out 20 different light patterns and a variety of different colors.
In addition to being waterproof, the device offers a stainless steel anti-theft strap, 2 year manufacturer warranty and up to 40 hours of runtime. Check out a demo video after the break.
