1998 Q45 turn signal working intermediately

Hello all, I am getting old and sometimes my brain does not engage fully. I do have a problem that maybe someone who is awake can help with.
When I engage the turn signal (any direction) some times it blinks for a few times, then stops, with the lever still engaged. Sometimes it works throughout the whole turn; sometimes 3 to 5 times then :banghead:. Does anyone have any sugggestions as to the problem?...Thank you in advance.

Check that all signal bulbs are OEM or Sylvania LL only. Check sockets for corrosion, and check all wires at socket.

If this is all good, time to look at turn signal switch.
