Lumicycle launch inSight LED brake light

New light doubles as a tail and brake light with an accelerometer to detect braking forces

Here's a neat idea, the new  inSight from light manufacturer Lumicycle is not only a powerful rear light, it is also a brake light. It houses an array of Cree LEDs and they're activated when the internal accelerometer detects braking forces, with an ouput of 200 Lumens when braking, or 50 Lumens when used as a rear light.

You can run the inSight as a rear light only with a steady or flashing mode, with the Cree LEDs provide a 50 Lumen output. One mode provides a combined tail and brake light, while another mode sees it operating solely as a brake light, an ideal option for daytime use. In braking mode the light pushes out 200 Lumens, which sure ensure it's hard to miss for other road users.

British company Lumicycle developed the inSight citing government figures that “over 25% of all cycle fatalities happen during daylight with the cyclist being hit from behind,” and reckons the inSight  “will revolutionise the cycling industry in terms of both safety and visibility.”

The internal sensors monitor g force constantly to determine when the bicycle is slowing, and they claim the software they've developed can prevent accidental triggering when say riding over a rough surfaced road or through corners. To further prevent accidental operation, the light also has a Patent Pending “self learning” and “terrain following” algorithm. This, says the company, automatically adjusts sensitivity to compensate for on and off road conditions, or changing surfaces and riding conditions. Furthermore, the brake light stays on for a short period after you have  stopped braking.

The light uses a 2Ah Lithium Ion battery which they claim provides a 24-hour duration, with an external battery level indicator. The battery can easily be charged, and a battery pack can also be plugged in to extend the operation time.

It's constructed from aluminium and can be mounted to the seatpost either horizontally or vertically, with adjustment to keep the light level.

The inSight will be available in May and will cost £79.95, they're currently taking pre-orders with a £5 deposit. More info at

He's a seasoned cyclist of all disciplines, from road to mountain biking, touring to cyclo-cross, he only wishes he had time to ride them all. He's mildly competitive, though he'll never admit it, and is a frequent road racer but is too lazy to do really well. He currently resides in the Cotswolds, and you can now find him over on his own YouTube channel David Arthur - Just Ride Bikes
