Underglow laws vary from state to state. Use this guide to check the rules where you drive, then see our RGBIC underglow kit and the step-by-step install guide.

Is Underglow Legal in My State? A US Guide (2026)

Two rules are nearly universal across the US: no red light shown to the front and no blue underglow (both reserved for emergency vehicles), and no flashing, rotating, or strobing while driving. Beyond that, states differ widely, from permissive (Ohio, Kansas) to white-only (New York) to not road-legal at all (Massachusetts, Virginia, Washington, Pennsylvania, and others). Find your state below.

Parked or on private property: On genuinely private property, a private lot, driveway, car show, or off-road, underglow use is generally far less restricted. It is not a blanket "legal when parked" rule, though. A car parked on a public street is usually still treated as being on the highway, so the color limits still apply, and red or blue can trigger separate police-impersonation laws regardless of motion. Keep to compliant colors and check local ordinances.
