With LED blinkers it's kinda simple to add 4 way flasher wiring. This is for neg ground, the diodes would be reversed for pos ground.

Intrending to add the switch here:

Need a simple on-off switch that will mount to a 1" frame rail. All that I can find are for 7/8" handlebars. Anybody have a suggestion?
 
If the flasher relay is after the ignition switch, your solution will make 4-way flashing possible without ignition on.
 
I have had 2 "modern" motorcycles with this feature. I used the 4 way one dark night when I needed to make my bladder glader on a state highway. I was able to park about 6 feet off the right shoulder leaving about 12 feet to the outer line of the right lane, almost no traffic. I got into the woods...On the way back to the bike I see a pickup pass within inches of the left handle bar and make an obvious, and quick, course correction. Was the driver OUI or a victim of target fixation?

So, why do you want this feature?

In any event, I suggest that you utilize the electronic relays, the electromechanical, dissimilar metal, points type relays draw a lot of power and can suck down a battery rather quickly. I am impressed with the wiring diagram you have and 'am thinking that you may find a single relay (electronic box) something like: Amazon product ASIN B001KSGF14 that has both functions, not sure.

Best.
 
Harley’s use 1” handlebars, search for an accessory switch for that.

Have any friends with 3D printers? I have been designing and 3D printing those kinds of things when the need arises. You get exactly what you want, fits perfectly.

They don't draw any current at all, they simply open the circuit when bulb current heats them up. But they don't work with LEDs anyway.

All I can suggest is checking out Mouser, Digi-Key and Waytek Wire [better prices] for your on/off switch. If you have [or install] a Lucas [or clone] 4 position ignition switch, like used on the Mk III, you will have an "accessory" position. That would eliminate the "non stock" switch. A downside of your switch location is: Joe busybody or his kid, comes along while you are in the pub, having a pint. Gee, I wonder what this switch does?? Hours later, you come out to a dead battery! :eek: 4 Position ignition switch eliminates that scenario.
I also found this electronic flasher unit for LED lamps. You can even adjust the flash rate. Best of all, it's not expensive [like other suggestion]. See

Amazon product ASIN B07D33JGLC

PS Slightly cheaper but not adjustable flasher

Amazon product ASIN B07JFPXM21

I think you mean if the power wire bypasses the ignition switch? Placing the flasher, or the power source wire after the ignition switch means it only works with the ignition in the "run" position.
