7. Under Body Neon Lights
For decades, laws have prohibited the use of adding flashing red and blue lights to vehicles to keep people from acting like the police. People have used faux police lights to zoom through busy traffic with ease since the other drivers thought they were letting the police go by.

But when neon lights became popular in the early 2000s, things got even more complicated. When done right, neon can look cool, but still, having an underbody glow can distract other motorists. And that can cause accidents, and eventually a ticket.
