My Nighthawk rear turnsignals were falling off. I couldn't get replacement stalks, so I opted for universals that looked similar. I preferred DOT approved to know they would be bright. The DOT approval more than doubles the cost from non DOT lights, but I don't know how bright the non DOT lights are. From other reviews, I would assume the non DOT lights are not this bright. These lights are about 75% as big as the stock, look very similar and are equally bright. Easy install. I would use these again.
