There is a lot to keep track of when riding a motorcycle. Your hands and feet are busy with steering, throttle, shifting, and braking while your eyes and ears are paying attention to threats and hazards while deciding the best path for your motorcycle to travel. One area that is not as easy to keep track of and control is what is happening behind you. There is no rear view mirror on a motorcycle and the side view mirrors do not always give you a clear indication of what is happening behind you. One thing that you can do is utilize your brake lights to indicate to those behind you that you are slowing down even though letting off the throttle would have been enough to achieve the desired speed. With that in mind I decided to install a brake light modulator on the SFV650 to add some attention grabbing flashes when the front or rear brake is applied.
There are a few options out there for brake light modulators and I installed the SupaBrake-II from Vizi-Tec for a few reasons:
- It was supplied with a wiring harness specific to the brake light harness on the SFV650 so there was no need to cut into or splice the existing wiring harness.
- The modulator unit includes nine different brake light profiles.
- The duration of the brake light burst is a function of when the brakes were last used. In stop and go traffic the brake light won’t continue to flash and annoy the drive behind you or become its own distraction.
- It can be turned off if necessary without removal.
Although the brake light modulator unit is plug and play, you still need to locate the existing wiring harness and make the connection.
To get to the wiring harness it was necessary to remove the right side body work (Allen bolts, Velcro, and pop rivet) and the right side passenger grab handle (2 Allen bolts with blue Loctite) to get into the area where the harness was located. Once those pieces were removed, the harness could be eased out from between the frame and rear fender trim. The harness is shown in the yellow circle and the one of the grab handle bolts in the green circle in the photo below.
Once the existing connector is separated you insert the SupaBrake-II unit.
Then it is just a matter of neatly arranging the wires and buttoning things back up.
It is hard to show the operation of the unit without someone trying to follow you and take a video in the different scenarios, but I did locate a YouTube clip that does a pretty good presentation of the operation of the unit. SupaBrake-II Demonstration.
