Clever LED Bike Light Has an Accelerometer to Sense When You Brake

Sure, you could wear a Safe Turn indicator for night rides, but why lift your arm when the Spooklight has a wireless handlebar touchpad. Its accelerometer also shines your brake light when you slow down—just like a car.

The LEDs are super bright, and a built-in lithium polymer battery keeps them juiced for about 60 hours. At that point the Spooklight comes off the bike and charges via USB. And this is pretty cool: it will also charge your gadgets (like MP3 players and cellphones) while you're on the road.

£55 ($88) is on the pricey side, given you can still just wave your arm to change lanes, but if you ride about at night quite often, it could be a good investment in your own safety. Either way, points for the clever use of the three-axis accelerometer. [50Cycles via Wired]

Two comments:

1) the turn signal really doesn't work effectively because the light (and the bike) are too narrow to allow drivers to differentiate. Look at how motorcycles handle it and you'll get some idea of just how little space there is there.

2) there is much simpler (and more reliable) technology out there already (you can get it via Nashbar). A small lever-type microswitch clamps to the brake cable and housing at the rear brake, and when you squeeze the rear lever, the lever triggers the switch and the taillight illuminates. Simple and cheap, and you can also "tap" it to signal "back off" before braking.

Of course, this one will work on a bike with disk brakes and the simple approach likely wouldn't, but most bikes don't use disks. #spooklightaccelerometerlight
