Legality of Neon or 'Underglow' Car Lights Keep Attracting FindLaw Visitors

By Steven Tanner on May 14, 2012 6:55 AM

It seems a lot of car buffs out there like the look of their cars "floating" down the highway atop a pillow of purple light. Perhaps you've seen cars modified with these neon (or LED) "underglow" lights before, often with other aftermarket adornments such as ornate wheel rims or tinted windows.

Depending on your point of view, they are either super-cool or super-distracting. Either way, this is one of our most consistently popular pieces of content on As one of our more popular Law & Daily Life blog posts asked nearly three years ago, "Are neon or 'underglow' car lights legal?

Well, it depends.

If you live in Kansas, for example, "any motor vehicle may be equipped with neon ground effect lighting" so long as it does not flash, is not red in color, and that the neon tubes (or LED bulbs) themselves are not visible. That's according to Chapter 8, Article 17, section 8-1723(f) of Kansas Statutes.

Why not red? Some states also ban blue, but the point is to prevent any possible confusion with police cruisers and emergency vehicles.

Arizona motorists are limited to only amber or white lights on the side portions of their vehicles, which may not allow for the desired "floating" look. If you live in Michigan, forget about it.

Don't live in Kansas, Arizona, or Michigan?
