Hi. It is the top middle light with wolf logo & it's just blinking while driving. It is a brake light, when presses it does solid like it's supposed to.
There are some after market LED bulbs that will do what you describe, supposed to draw attention for safety. Is the blinking LED different from the others?

My 2021 Wolf Pup does the same thing, Middle light flashes not hard or long just sort of flickers (middle light only) I would think it would be annoying to anyone following me maybe even dangerous??
