Fabric FLR30 Bicycle Tail Light Shines Brighter When You Slow Down


Rear lights for bicycles usually consist of a feint red light that’s always on to make it easy for motorists to spot you from behind. The Fabric FLR30 does that, too, but adds a clever trick – it shines brighter as you slow down to inform motorists and other cyclists that you’re stepping on the brakes.

That’s right, this bike light can recognize whenever you slow down or hit the brakes, allowing it to serve as a functional brake light. No, you don’t wire it to the braking system, either, as it relies on an accelerometer to determine the bike’s motion, enabling to instantly recognize a decrease in speed.


The Fabric FLR30 measures 2.9 x 0.9 inches (length x diameter), with a maximum brightness of 30 lumens, although it shines a whole lot lower than that until you actually hit the brakes. A bundled mounting bracket can be strapped down to a variety of fixtures, allowing you to mount the light on the seat post, the rear section of the bike frame, and even the back of your helmet.


Designed for rugged outdoor use, it’s housed in a durable nylon case that’s IPX5-rated for waterproofing, ensuring it can handle the elements with ease. It comes with an integrated battery that can burn between eight to 12 hours, depending on your choice of settings.

Available now, the Fabric FLR30 is priced at $39.99.
