ANYTHING can be made to fit. You will need a different flasher relay with a timer and the logic to accept both buttons at once , but I guess you knew that.
Yeah...already have the module and wiring figured out just haven't decided if I want to put up with the same $hit watcher did when he put his fairing, etc on
Motogadget in Germany have some too. So do ISR in Sweden.
But this must be a US thing - I really HATED the Harley indicator system when I had my Softail.
Hazard flasher fitment is a piece of cake - Cheap switch - two wires and load independent relay - about 30 bucks all in at a guess. Had it on my R3 for a while - then found something that does it automatically when you brake hard.
