Don't know of one, but.......

I have never towed a trailer with LED lights. Approximately half of the rentals have caused my X5 to blink fast, half are fine. It often switches to high speed part way down the road. It isn't an LED issue, it is a current issue. Perhaps LEDs can cause that, I don't know, but in my case it was the ground connection between the trailer and the vehicle.
