Whelen headlight flasher on OEM LED headlight.

Question....I’m working on a 2019 F250 and attempting to flash the front LED “c rings”-not the actual headlight. I am having difficulty getting it done and appears to be a grounding issue. I’m not very familiar with ford factory LED headlights so here I am. While using my power probe I can get the flasher to work, but off the trucks power the flasher will activate and you can hear it operating, but the light will not flash. Any info will help!

So theres actually a company called wicked warnings that has a flasher made specifically for that. Comes with wiring diagram and everything. It's been a long time since I've done one but if I remember right I believe they are positive switched so you would need a relay to cut off constant power to them
