|The GS-100A Strobe Controller for LED Stoplight|
"It got your attention, didn't it?"
I really couldn't argue with that, and it was ever so eloquent when compared to the diatribe I was about to launch into. It is supposed to enhance a riders safety, as the only thing we have back there to let folks know what is going on are three small indicators, one of which protects your life by alerting people behind you, but it is usually smaller in size than a softball. Anyhow, I've put over 200,000 kilometres on various bikes that mount them and have not once been questioned by law enforcement nor border/customs officials.

There are a ton of installation How-Tos on the interwebs, so I'm not going to steal their thunder, suffice to say that I'll try to give you some model specific details for a 2004 Honda Shadow.
CAUTION!!! Some viewers may find the following images of a well ridden, dirty, adventure wanna be Honda Shadow disturbing or offensive. Those offended may want to ensure they are comfortably seated, have their pacifier/soother along with a blindfold close to hand, and a Sharon, Lois & Bram recording ready to play. Or as Caroline puts it "sorry not sorry for the filthiness of my bike".
|Why doesn't she keep it clean and safely parked in the garage with the polish rags!?|
1. You will want to have the drivers seat off so you can access the three connectors protected by a rubber sleeve that rests on top of the battery cover top thingy.
2. Locate the one with three conductors using a white plastic connector. The three wire colours are:
- green with yellow stripe.
3. On the male portion of the connector whose wires head towards the rear of the motorcycle, Cut two of the wires leaving enough room at the connector to solder or splice in the future. I would leave minimum 3/4" at the connector side. You want to cut the green and the green-yellow stripe. Leave the brown run light untouched.
NOTE: My friend Jeff advocates purchasing identical harness connectors so the bike can be put back to stock easily for sale or for inspection if needed. "...I cut nothing.. always make or buy adapters to plug in and go back to the way it was."
Update:I've since seen a diagram where the installer cut only one of the wires, and simply connected the other wire in parallel. I've added this below for your reference. It's always a good idea NOT to cut unnecessary wiring if you can manage it.

The black wires are all connected (tapped) onto the green ground wire of the bike
4. For reference, the wiring diagram breaks it out as follows:
- Green = frame ground
- Brown = run light (always on) 12V
- Green-Yellow = Brake light (only on when brakes applied) 12V
5. Orient your GS-100A correctly, and connect the "IN" side to the forward part of the motorcycle, and the "OUT" to the wires continuing on to the back of the motorcycle. My girlfriend opted to use bullet connectors to do this, the idea being that if the module failed, she could simply remove it and plug the harness back together. Ensure your finished cable and module are routed UNDER the frame rail and not OVER TOP of it.
Note that we disconnected the strobe and rerouted the cable after our testing, then tested again once it was secured to the frame rails out of the way of contact with the seat.
And now, for your enjoyment, a video showing the completed job. Caroline replaced her analogue 1157 bulb with an LED one that she purchased on Amazon.ca, so her bulb appears quite bright in this video. Your mileage may vary.
The GS-100A will apparently work with both analogue AND LED bulbs, but the pattern changes a touch as the analogue bulbs can't respond to the quick flash voltage spikes the same way.
This video by Gary Rowe highlights the differences you might expect to see:
Caroline has been riding with the brake flasher for almost a week now, although has only gone out on a few rides. Some observations of mine:
- Try to engage the brakes for a three second or longer period as opposed to "blipping" them on and off. Not only is it a good habit to get into, drivers won't shout out that "Your brake light is broken!" when you get to the stop lights. If you are in the habit of a brief touch now and then, all we will see behind you is your brake light madly flashing away unless you hold the switch activated a tad longer.
- It really does work to improve visibility, as I have a tendency to ride a bit too close to Caroline when following her, and she used to catch me by surprise with braking once in a while, but it's got me backing off a bit more which is a good thing. In my own experience, I note that some drivers leave me more room behind the bike as well. Not always, but the difference has been noticeable.
What have you done to make your ride safer this season?
