My Tuckers part had issues as well, with internal shorts in those flimsy blades causing it to behave as if emergency hazards were on.
Haven't had much luck fiddling with the bends and tension. All will be working well on the bench, but by the time i get it all installed, I only have rear blinkers working; no fronts. Those blades just seem awfully flimsy. I would like to see a pic of your bobby pin mod if you have one. I hate to spend money on another switch that may or may not work.
