Hi, jelorean. I have a 2008 Speed Triple and had a similar issue when i went led on all my lights and indicators. As sokn as i installed tbe new parts, my lights and turn indicators had a variety of glitches, including what you describe.
In my case it was the led turnsignals that did not include a load balancer that was the problem. As soon as i installed a load balancer in the turn indicator circuit, it all worked.
Additionally, some led headlight kits require a different lighting relay module and do not include it in ghe kit. Hope this helps.
