Blue Headlamps on Super Stock cars

There are so many modern cars running light blue, pink, purple....you name it out here in So. Cal. I know its illegal but you'd think these guys would have been ticketed by now. The blue I speak of is the blue R3 bulb headlights, not sealed beam. Buddies dad had a 66 Comet Cyclone 390 with blue dots on the back, finally got a ticket for them......
