Hawaii Neon Underglow Laws

Hawaii neon underglow usage is governed by the state's Code. All relevant laws, rules and regulations pertaining to vehicle lighting including car underglow in Hawaii have been provided below. Make sure to examine the regulations carefully and do not use any restricted lights.

Usage of neon underglow lighting is governed by Hawaii Vehicle Code, Division 1: Government, Title 17: Motor and Other Vehicles, Chapter 291: Traffic Violations, Part II: Equipment.

Is neon underglow legal in Hawaii?

Hawaii law does not restrict additional aftermarket vehicle lighting which would include neon underglow. Therefore it’s our conclusion that in Hawaii neon underglow is not illegal, as long as you follow these restrictions:

  • Red and blue colors are not permitted
  • License plate illumination must be white

Though not specifically restricted, we strongly suggest avoiding any kind of flashing, rotating or oscillating undercarriage lighting. These are considered a distraction and may be subject to other regulations.

We also recommend avoiding colors green and violet on any aftermarket lights including underbody glow, as these colors are typically used on emergency vehicles.

In all cases you should avoid red and blue colors on any aftermarket lights installed on your car. Blue color or a combination of blue and red is punishable by law with a fine up to $1,000, or up to 1 year in prison, or even both.

There are no relevant HI laws which specifically restrict or prohibit installing car underglow, meaning we consider it legal to use it while driving.

Sec. 15-19.1 Scope and effect of regulations.

Honolulu Police Department’s website has a page (link) specifically about neon underglow where it’s stated that these lights are illegal to use. We consider this information inaccurate (see: 15-19.1 above allowing any additional accessories as long as they’re not in violation), so use at your own risk.

We strongly recommend double-checking with your local police department. Feel free to get in touch with us in case you get a conclusive response!
