The Bike Balls are bicycle tail lights that are shaped like a pair of testicles, and swing merrily to and fro as you bike along. Developed by a pair of Toronto-based designers, these tail lights will catch motorists' attention and put a smile on their faces as well -- a rare occurrence given motorists tend to do everything but smile at cyclists they're sharing the road with.
The Bike Balls consist of a waterproof silicone sack which contains a red LED module. Users can turn the device on and switch it between steady and flashing modes by squeezing a button on top. The device can be hung from the bike's saddles and secured using a zip-tie.
These nutty bike lights are currently the subject of a Kickstarter campaign that has long passed its fundraising target, so don't be surprised if you see these cheeky tail-lights bobbing around on a bike in front of you.
