Okay...

Red and Blue are the absolute worst. If running Blue lights, you can be arrested for impersonating a police officer. If running Red lights, you can be arrested for impersonating an emergency personal. Either will have heavy fines, vehicle being impounded, and possible jail time.

HID Kits are 100% illegal per Federal Law for road use unless they are equipped on the vehicle from the manufacturer. This is because they are not DOT approved and once again is Federal Law...not state or local. This includes retrofitting an OEM HID Kit onto a vehicle it was not meant to be on. With that being said, you can get a ticket for ANY color including solid white. However, the more unique your color is, the more attention you will receive including the police. Don't want a ticket, don't run Pink HID lights because it is going to happen. When I personally run unique colors on my vehicles, I am fully aware of the risk and will happily pay the ticket since I am in the wrong. The same as window tint...I have received 4 tickets for illegal tint in the past 3 years including one 2 weeks ago. I know it is too dark, but I want it, I will not change it, so I pay the ticket.

With all that being said, most any exterior modifications are considered illegal. Lowering your is illegal if lowered too much, raising your vehicle is illegal if raised up too much. Tinting or covering your taillights and/or headlights is highly illegal...remember the GTO blackout covers that used to be popular?

The list can go and on, it simply depends on the police officer if he cares or not. Either way, if you decide to mod your vehicle then there is a chance something you have changed can be viewed as illegal.
