I find yelling effective, but this might just be of my location where music is played at a reasonable level. Don't need to move my hands to activate and easy to modulate from "passing through" to "I'm here, don't back into me!".
Another effective item is a 1,400 lumen lamp. Set to strobe as needed.
You know, I would pay for something that integrates a two stage horn (announce or loud) and push to strobe lamp; remotely switched by buttons in the handlebar wrap on the brifter. (think electronic shifting buttons and remote shifting buttons).
