Anyone have any experience with these Hella Dynaview lights? They are running lights that have a 2nd light on the left and right side that are controlled with a yaw sensor. Sort of like the turn assistance lights on many cars - but these are not controlled with directionals - the yaw sensor automatically kicks them on when the truck turns left or right.

I'm wondering how well they really work...
