The Vololights “Brakeless Deceleration Indicator”

Shari Ives Cool Stuff

The Vololights Brakeless Deceleration Indicator gives warning to following traffic when the motorcycle decelerates. They consist of a license plate surround, which houses the Vololights system. This system has two high outputs, LEDs, and the electronics, which are built into the top and bottom center of the housing. The only wiring required is the attached positive and ground leads.

The Vololights Brakeless Deceleration Indicator enhances the overall safety of a rider with its warning visual output alerts and functions as an auxiliary brake light. The user can program one of the three sensitivity settings for optimal performance. Touring for the most sensitive setting is great for larger motorcycles. Default is the standard setting and should work for most bikes. Sport is the least sensitive and works best for lower geared bikes.

There are two mode settings: Flash, provides alternating output at two rates between the top and the bottom LEDs, and Steady, which provides output from both LEDs simultaneously with no rate patterns.

A motion sensor is used to measure accelerations, and it is key to envision, designing, building and testing the deceleration device. These types of devices are not new from the point of view of physics, but we are seeing more devices that leverage new technologies.

Deceleration is brought about by one or more factors. Rolling off the throttle to let gravity and loss of momentum take its course, downshifting or use of the brakes. The settings for the device have to be accurate for the specific motorcycle, or a rider style output can be inconsistent.

Installation is simple, but you do want to make sure to have the normal 4×7 template. First, make sure the ribbon connector vertically between the lower and upper module sits up a bit in the middle.  Second, the back section has a right molded line that is meant to act as an alignment stopper for perfectly sized plates. Finally, the two electronic modules need to be loosened from their small screw mounts so there is enough clearance to slide the license plate in.

Calibration needs to be done after the final installation; however, this needs to be a two-person job. Once everything is in place it is time to test it on the road.
