It's hard enough trying to get drivers to see motorcycles in the first place, let alone depend on them to notice when you're decelerating in front of their car. Whether you downshift or just rely on engine braking, a motorcycle can slow rapidly, but the brake light only comes on when you actually apply the brakes, but not anymore. GearBrake flashes your brake light anytime you're slowing rapidly, even if you never touch the brake lever.
GearBrake knows when you engine brake and flashes the brake light briefly to let drivers know you're slowing. It uses an internal accelerometer that's calibrated to only activate under rapid deceleration. When you use your brakes, GearBrake also flashes your brake light for 2 seconds and then goes to solid for as long as you hold the brake.
The unit is simple to install, you just find any good spot, under the seat usually works, apply the velcro tape to secure it then connect it to your wiring harness, it takes about 15 minutes and a pair of pliers. Then you just forget about it and ride as usual, but now the driver behind you gets an extra warning whenever you slow down.
This is a really nice use of technology, useful, unobtrusive and it just might save your life.
GearBrake is available now on Amazon.
