well i got pulled over in madison for them.
right as i got on 441 I stopped at a gas station right off i20 to pee, and i pulled out and he was waiting in the turn lane for me to pass him. He pulled me over and said he didn't know if they were legal or not and had to call his supervisor. I ended up not having a recent insurance card in the car so I got a ticket, but I already had it dropped.
But i past several people with different color headlights so I was like wtf. maybe it was because I was from out of state or something idk.
the cop was really nice though.
