The biggest and most important reason is the fact underglow is considered a distraction.
While we at NeonLaws.com clearly do not completely agree with this assessment, we’ll do our best to give some reasoning in order to help you understand why car underglow is sometimes illegal.
If you look at it objectively, underglow is a decorative, vanity item.
It’s not essential for the operation of your car in any way.
Some car owners believe it makes their vehicles look better or cooler, while some disagree. Regardless, if you made the choice to install it on your car and drive with the lighting on then you believe it makes your car look better.
While driving, you’re the only who does not see the underbody glow.
