Has anyone added a hazard light?

The lack of hazard light seems like a huge oversight to me. Such a simple and useful thing.

Tempted to get a switch like this and mount it on the left speedo infill panel. There's a brief topic on VFRW, but not much.

You will need, at minimum, a double pole/double throw switch; the one you have linked will not work.  We have dual filament bulbs where one is responsible for the running light function and the other filament is signalling.  A standard DPDT switch will work with some diodes or a TPDT without.

Pole 1 - the switch should interrupt the brown/blue wire entering the normal switchgear.  This pole should be normally closed and you will only output from one throw.  Basically, when you flip the hazards on, you want to break the circuit for the running light filaments.  The stock switch does this for the running light filaments of the side you are signalling toward.

Pole 2 (&3 if TPDT) - You want power from solid grey to BOTH orange and light blue wires.  The standard signal switch only applies power to one of the two wires and the relay handles the switching of power on grey to flash the lights.  The wiring here is variable and I will draw up a quick schematic to follow.

Not so on euro/uk version. They just do signalling. So that switch might still work.

Are you sure?  I'd be interested to see the schematic, since I think you have a different headlight switch than us too. 

But yes, if you don't have to interrupt the running light function, then you can get by with a SPST switch and diodes.

I'm 100% sure that the UK model and the euro model do not have the signal lights as running lights. Just signalling. Let me see what i can dig up in the way of schematics....

didn't know the headlight switch was different.

Yep found it on the A5-HISS schematic.  You lucky bastards get flash to pass built into your HL switch.

So yes, you can do it with that SPST switch in 2 different ways.

1.  Splice into grey (don't cut it) and wire that to terminal 2 and output from terminal 3 with two diodes in parallel.  Splice into orange and light blue and connect to the diodes.  Without the diodes, using the regular turn signal will turn into hazard flashers.  Which leads us to option 2.

2.  Option 2 works as a combination of both the signal switch and the flasher.  Use the SPST switch to connect orange to light blue.  Turn on signal in either direction then flip the hazard switch to energize all the signals.

I didn't talk about the other terminals though.  Looks like connecting ground to term 8 will light up the big bulb on the switch and it will flash.  Terminals 6 and 7 can be connected to constant 12V and ground (respectively) if you want the small bulb on the switch to be lit up all the time.

That's some fully useful info right there!

Really appreciated!

I think if i do this, i'll wire it so that that just flipping the hazard switch activates all signals, AND makes the switch bulb flash.

Some Euro-spec Honda models had hazard light circuits already, e.g., the Pan-European.  That LHS switch pod is way too big for a VFR, but my reason for mentioning this is that there may indeed be other Honda models that had factory hazards--and so will already have the switch you want.  You'd still have to fabricate the diode circuit in order to make the switch work, but at least you'd have an OEM look (which would be important to me, anyway).

Found on Web.

Ciao,

Fair point about the OEM look. Hell, pretty much any Japanese bike unit would probably work provided it wasn't too wide and i could either drill a new location pin receiving hole or otherwise fix that.

Check into the 6th gens as well. They have hazard lights. Might be an easier conversion.

A fine suggestion.

Was going to suggest the 6th Gen switch pod assembly also, but no idea on how to wire it. Not sure when it was added to the 6th Gen. They didn't come like that from 2002, but by '08 they had a switch on the right handlebar for hazards.

My 06 had them. Thought all the 6ths did. Odd thing to add mid-run, but that's Honda for ya.

I'm not sure if your LED mounting brackets would pass a vehicle inspection. They would skin a cat at speed!!!!
