4-way flashers on 2013 CB1000R

I can't even believe it's legal! The first-gen CB1000R came to North America (at least) with no hazard lights! Fzcking stupid! Getting rear-ended in a car might be unpleasant, but on a bike it could easily be fatal! But, anyway, I decided to change that. I'm not very electrically competent, but I got some input from Ghostrider.1127, and especially from DELUth (many thanks, as always, Dylan!)

First, ta-da! The show:

( not sure if the Vimeo file will show...)

well, the video seems to be failing, but here's what I did:

first bought one of these:

and one of these:

(more heavy duty than necessary, but I wanted fully electronic, not electro-mechanical, and, what the hell, all cheap, eh?)

first order of business was to run power direct from the battery, cuz I wanted the flasher to work even when the bike was 'down'. and because it's hard to feed to various wires and bits, i decided to 'break' the run: first section, battery to a waterproof connector in the headlamp nacelle - about 5 ft of 16 guage wire, with a 10 amp fuse at the feed end:

second, connector to switch, (and back) to output:

output (power) connects to X terminal on the flasher; L terminal (load) on flasher connects thru a pair of diodes to the bike circuitry. the diodes are necessary to keep power from flowing 'backwards' into the 'wrong' flashers when the normal turn signals are operated. almost anything will do - any electronics store will be able to supply something suitable. I used this diagram plus some input from Dylan to figure out what to do:

the scary part for me was to cut into the OEM bike wiring - I had NEVER done this before! in the end, i decided to strip the insulation from about 10mm of the correct BLUE and ORANGE feeds to the front turn signals; to wrap the 'feed' wires ( I used 18 gauge from the flasher L terminal onwards); to solder; and to tape like hell! I live in a wet land...

another big challenge was where to fit everything. space is tight in a modern bike! eventually, I ran the feed in to the space behind the headlamp; fitted the flasher unto up high beside the left fork; and ran the 'feed' wires parallel to other wiring out to the 'front' of the headlamp unit, where the junctions needed to be made into the OEM wiring. the 'new' wring is visible as red in this photo (there is a black too, but that's hard to pick out...)

up front, where my flasher wiring connected to the turn signal wiring. you cut into the BLUE and ORANGE... ( check the wiring diagram)

finally, positioning the switch - as per your preference...

oh, almost forgot to mention... it's wet where I live, so I sealed the entire 'back-end' of the flasher unit with epoxy before submitting to the environment:

Good job, Don.

Maybe you won't get squished on the side of the road, now.
