Has anyone messed around at all with their turn indicator circuit to add a hazard flash function? I'm planning to wire in something to enable this, but I don't know what the bike's actual flasher relay circuit looks like or even where to go looking for it. Hoping I can do something simple along the lines of this:

I was just thinking about the same, looked on YouTube but have only seen other bikes (like SV650)

would be perfect using it during lane splitting in rush hour / in heavy rain / night commute ...

in the SV650 it was under the seat, not sure where it'd be in the SCR

Just snag a left handlebar control for a European spec bike. It'll have flashers, plus the ability to turn off the headlight.

So much easier said than done. I've done quite a bit of searching with no luck so far.

.....if you are convinced simply switching the controls would work (and I’m not so sure myself), looks like you’d need Part 19 on this diagram (P/N BL3-83972-00).

Surely it requires a functionality that US-spec bikes don’t have though, doesn’t it? In layman’s terms - no point having a switch to flash your lights, if the bike doesn’t have the ability to? Wouldn’t it need some relay work too?

My bike has that flash trigger for the headlight. I've heard it referred to as the Flash to Pass button.
I think this discussion is about a hazard flasher which blinks all your turn indicators at once. My Virago 1100 had that function.

I believe you guys in the U.K. Flash your headlights for a different reason, as in giving someone the ok to advance.

We all do it for different reasons - that’s part of the problem!!! :laugh:

We’d generally put them all on at once if we’d broken down at the side of the road, as a warning.

Would you guys have them all going at once when filtering (lane splitting) then?!

That's what I intend to use hazard function for. The "flash-to-pass" button is on US bikes - that's the little trigger on top of the left hand control that activates the high-beam headlight. A hazard function would make the turn indicators flash in unison. If I understand the circuit diagram that I linked below (which admittedly is for a muuuuuch simpler circuit from an old Volkswagen than what actually exists on our bikes), a switch wired to the correct pin of the flash relay would create the desired effect.

My hope is that they fab the bikes with that pin wired into the cable regardless of where the bike is headed and I would just need to connect a switch at the handlebar. If an EU/UK control could be swapped in, and that hazard button was on there, that would be an easy enough solution. Too many ifs ...

Fair enough then! If you need help sourcing one, let me know.
