FireFlies Tire Valve Stem Light is a unique tire valve stem light that produces streaks of bright blue light when your vehicle is motion. It can be attached to the tires of any vehicle whether it is a car, truck, motorcycle, or even a bicycle. It has an automatic on and off function that works on the concept of centrifugal forces, so there is no need for the hassle of switches. When your vehicle is in motion, the LED light illuminates a deep blue streak. The LED light is housed in a tall acrylic diffusing tower and is powered by three AG10 button cells.

Easy to Assemble

Assembling the stem light is extremely easy. First you have to pull out the plastic insulator from the side and dispose of it. Once the insulator is removed, you will find a hosel, which is a collar like device, located at the inner edges. The hosel has a sawtooth pattern on one end while the other end is smooth. Orient the flat end so that it faces the stem light, and then screw in the hosel into the male threaded portion of the light. Now the stem light is ready to be connected to your vehicle, and it will switch on automatically once the car is in motion and turn off when the vehicle comes to a stop.

Safety with Style

The stem light is ideal for illuminating your vehicle so other drivers can see you. This is particularly useful when you’re riding a bicycle at night on a street with inadequate lighting. It is also an excellent way to add a bit of panache to your vehicle and give it a futuristic look like the vehicles from the Sci Fi movie, “Tron”.
