Kansas neon underglow use is regulated by Kansas Statute, Chapter 8, Article 17: Uniform Act Regulating Traffic; Equipment of Vehicles, Section 27: Additional lighting equipment permitted.
Is neon underglow legal in Kansas?
Kansas law specifically mentions and permits the usage of neon underglow. Therefore it’s our conclusion that in Kansas neon underglow is legal, provided you comply with the following restrictions:
- Underglow must not be red
- Lights must not be flashing
- Neon tubes must not be visible
Though not restricted by law, we recommend also avoiding blue and green colors on any aftermarket lights including underbody glow. Blue and green (along with red) are typically used on emergency vehicles, and using these colors is illegal in most other states.
In summary, Neon underglow is legal in Kansas on both public roads and private property.
