Why are \"Blue\" headlights illegal? A guy I work with was stopped by the Texas State Trooper because he has "Blue Daylighter" headlights in his truck. According to him, the trooper was a smarta$$ and didn't offer any reasons other than "they are illegal unless they are OE". I tend to believe him because he is 46, clean cut, and very laid back. I've never known him to speed or otherwise drive crazy. My question is. .. why do they sell them if they are illegal? You see BMW's, Mercedes, Lexus and a ton of Rice Rockets with those "wings" all over 'em....why aren't they stopped? I know most THP's are Di**less bastards even more than most cops, but what's up with this? I'm at 10th and Plum....10 miles from nowhere, and Plum out in the sticks....Stuck?...Hell no..I still got some gas left..
