Directionals flash at ignition on

Hi...I have an 2001 Fatboy with the security system. No alarm. Recently when I turn my ignition switch on the directionals flash rapidly. Bike runs fine. Should I be concerned? I checked the error codes D1 - D10 clr. I just can't figure out how to get this to stop. Any help suggestions would be appreciated

 

Try turning on each blinker and let it blink 5 or more times and see if it stops it. Also check the bulbs that they are all working.

 

Thanks Glider. Tried that. Directionals still flash. All bulbs in working order
