I have fitted a 2 pin LED flasher but I have only changed my front units to LED and it works fine.
I did read another post where they had used the 2 pin flasher with full LED units and the light on the dash did not go completely out between flashes.
They also said the Suzuki LED flasher is a 3 pin with the third pin being wired to earth, this ensured the light on the dash completely extinguished between flashes.

Ridding a motorcycle keeps things in balance.
At the end of each trail and at the end of each day history is made.
