2019 Beta 500RRS Replaced 4 Horns so Far.
Replaced 2 original horns and two after markets all failed.
Have normal voltage when hitting momentary switch and Ground is good.
All new worked after install then after a few rides no go.
Back to test voltage and all good.
No horn lighting off when not asking ( pushing horn button.
Not sure if we have a bad bunch of horns but that would make sense if one from Beta and different aftermarket K&S Horn
