I installed a simple AliExpress piezo buzzer on the flasher relay. $3

Perfect, keep it simple I always say. I have a BMW Z4 that doesn’t make that clicking noise when the signals are on and I always forget to cancel them. The device that makes that sound is on a circuit board behind the instrument cluster and a huge pain to replace. I may have to use something like that.

So then they don't work always then.
BTW that is not how they work.

Somewhat yes they do.

Yes, Harley-Davidson self-canceling turn signals primarily use the vehicle speed sensor (VSS) combined with a bank angle (tilt) sensor to determine when to turn off. The system calculates distance based on speed and cancels signals after a set number of flashes (usually around 20) or after completing a turn.
