Glow-In-Dark: Bike Water Bottle As Illumination

Flick a switch and your water bottle will glow. A new product from Topeak, the iGlowCageB, is a bottle cage with an LED at its base.

In the march toward more visibility for night bikers, this week Topeak unveiled something new. With the iGlowCageB a rider can fill up with water and the cage-light then uses the bottle and its liquid contents as a lamp of sorts.

There are multiple modes, letting a user switch through colors including red, green, purple, and blue light. Match your bike graphics, perhaps, or your mood.

The company is touting 360 degree visibility with the product, though obviously your legs and the frame will get in the way.

The added light is nice, and it will increase a rider’s visibility from the sides, but the bottle should only add to more traditional night-biking products like a rear red blinking light and a front-mounted white beam.

It blinks or shines a solid beam. Its LED runs off two CR2032 batteries, and Topeak notes burn times of up to 100 hours.

The cage is lightweight at under 2 ounces, and it fits standard bottles. See Topeak for more info, but price and availability is TBD.
