Headlights flashing on and off.

[needforspeed150]

When riding the other night with my 2021 Rocket 3, my headlights were flashing on and off at hiway speeds. When stopped they do not flash. I tried jarring the headlight when stopped and could not recreate the problem. I really don't want to take it to a dealer for this. I assume that it is something loose. A connection, etc. Has anyone here had any similar issues and if so what did it turn out being. Any ideas would be appreciated.

i would staqart with checking/tightening the battery terminals
a short in the tail lights might cause this prob.
