Just when you think your life is chock-full of awesome, along comes something like these FireFlys. They’re inserts that screw into the valve stem of your car or bike tyre and when movement is detected, they switch on and give you cool glowing tyre rims or spokes. Three batteries inside, not sure if they’re replaceable and comes in a pack of 4 (red/green/blue/yellow) for US$6.99.
Motion activated, flash automatically when the vehicle moves. Easy installment, simply screw it into the tire valve stem of your car, bicycles or motorcycle in seconds. Super bright, energy saving and long lifespan LED. Increases night time and bad weather visibility for safety. Made of durable metal and plastic

As a warning, I've known many people that ride motorcycles with these, and they tend to break the valve off if you accelerate and decelerate at regular bike speeds. So if you put them on, ride very slowly, don't want a flat tire at any speed on a bike!
I like the blue… is the lights flickering?
they switch on and give you cool glowing tyre rims or spokes.and it looks beautiful.
HELP ME OUT HERE…WHAT BATTERIES DO THEY USE?
