I've been meaning to strip mine down, the passenger high beam on mine sometime flicks off, only on bumpy road and only when the light is pointing fully left.
I can only guess it's a bad connector or almost broken wire if it only does it point left.
Problem is that it happens so infrequently that I forget to check it when I do have time.
Would be good to see inside one beforehand.
