all the things you mention are a distraction to other motorist, and have no place on city streets.
I like the way they make cars look for car shows but that is where it should end.

Well growing up and being directly involed with custom cars, race cars whatever you may call them, in my state NEONS are illegal and yes they are distracting to other driver’s especially on highways. On the cobalt I own we have the under lights, but we also have a switch to turn them off while driving on public roads. There are so many ways to have the fancy lights on your car and be able to obey the law. Yes some officers like it while others judge you by what you drive or even how you look. I had green reverse lights and got sited for it. Ticket cost me $110 bucks and what sucks is in my state you do not have to even have reverse lights to pass safety emissions. But never less the judge said the only colors of lights on your car can be amber, white and red. At custom shows and all its different, but I agree with the officers and understand where they are coming from. About a year ago my sister in law and I where driving down the road and because of this guy was to busy looking at my car he winded up ass ending another car... This is a prime example to why they should be off while on public roads. So my suggestion is to obey the laws have a way to turn them off while on public roads and have fun where it is acceptable.

In colorado you my not have any red or blue light emitting from the front of your vehicle. I have seen the under lights in our town, but the drivers only have them on the sides and are very well placed so the light doesn't emit to the front.

Hey Clove... Here it depends on the officer. Some of them will pull everyone over for the smallest things, usually the rookies, and there are some that only do it when we need to find out who is in the car. It's good PC and we have gotten a runnaway and concealed weapon that was involved in a burglary off of one of these stops so whatever works.
