Back around 2014 I was blinded by the first light bar I ever noticed. It was a sunny afternoon, I was driving away from the sun and the brightest 18" lightbar aimed higher than high beams was driving the other way. Blinded may be a minor exaggeration but between my variable tint glasses already being dark and a hazy windshield from a bad wiper that light bar certainly didn't help.
I ended up seeing that light almost every day for a couple years. Usually in the morning, never at night. It was some old guy in an old pickup truck. I have no idea how it helped him see, I kinda just think he wanted to prove what an asshole he was because the second or third time I saw him, I flashed my high beams and he flipped me off. He got to see my high beams every day after that.
