• Red/White/Blue LED light causes plastic case to glow brightly

These are labelled as bicycle Tireflys, and they contain an LED (a red/blue multicoloured LED in this case; emitting bright flashing light), packed by a transparency plastic bubble that glows brightly. They are designed to be screwed onto the valve stems of your bicycle tires ("tyres"). When you start pedalling your bicycle, the motion-sensitive switch inside the Tireflys will engage, turning the units on. The units will turn themselves off automatically after 10 seconds if no motion is detected. They also fits motor cars wheels!

How to use it

To use the Tireflys, remove them from the package with a sharp knife or a pair of household scissors. They have a set of batteries already installed, so you'll be ready to use them right off the bat.

On your bicycle tires, unscrew and remove the valve stem cover if they are present.

Screw the Tireflys onto the valve stem in their place, and that's it.
Yes, it really is as easy as that.

Replacing the batteries

To change the batteries when necessary, unscrew and remove the Tirefly from your tire's valve stem. Grasp the Tirefly in your hands, with one hand holding the top portion of the Tirefly and the other hand holding the lower portion of the Tirefly.

Twist counterclockwise (as if unscrewing); some vigor may be necessary, until the halves seperate. Be sure the light-emitting side faces the floor so those batteries don't just clatter all over the driveway or garage floor when the two halves come apart.

Tip the three used CR1330 (AG-10) cells out of the Tirefly's body and into your hand, and dispose of or recycle them as you see fit.

Insert three new CR1330 (AG-10) cells into the Tirefly's body, button-end (-) negative first. Place one cell at a time inside the body. When all three cells are in, screw the bottom half of the Tirefly firmly back on.

Gently whack the unit on the palm of your hand, light-end first (this assures the motion switch inside gets reset properly), then screw the Tirefly back onto your bicycle's tire valve stem.
