If you’re particularly keen on getting yourself some under dash led lights, you could possibly get away with it if you added a dimmer.

That way, if you’re cautious, your under dash lights won’t be as bright and noticeable from the outside of your car and won’t attract unwanted attention.

It’s always best to check the laws in your state regarding blue dash lights but as a general rule, any blue light visible from the outside of your vehicle would be considered illegal. If in doubt, find a police officer who can tell you what the law is regarding a blue light on car dashboard. You should be aware that you run the risk of being ticketed for impersonating an emergency vehicle, so it’s best to avoid it all together.

How about a dimmer?https://www.oznium.com/switches/rotary-led-dimmer


You should be fine. I have some RGB LED’s that shine on my gauges and from time to time I will turn them on and make them shine in a slow pattern and the whole inside of my car gets lit up and I have never been questioned. As long at the light itself cannot be seen outside of the car and you are not distracting other drivers, it should be fine. Just be careful about it.From the code itself:
32-5-241. Auxiliary lamps
d) Special restriction on lamps.

Any lighted lamp or illuminated device upon a motor vehicle other than head lamps, spot lamps, auxiliary lamps or flashing front direction signals which projects a beam of light of an intensity greater than 300 candlepower shall be so directed that no part of the beam will strike the level of the roadway on which the vehicle stands at a distance of more than 75 feet from the vehicle.

No person shall drive or move any vehicle or equipment upon any highway with any lamp or device thereon displaying a red light visible from directly in front of the center thereof. This section shall not apply to authorized emergency vehicles.

Any vehicle may be equipped with flashing lamps which may be used for the purpose of warning the operators of other vehicles of the presence of a vehicular traffic hazard requiring the exercise of unusual care in approaching, overtaking or passing, and when so equipped may display such warning in addition to any other warning signals required by this section. The lamps used to display such warning to the front shall be mounted at the same level and as widely spaced laterally as practicable and shall display simultaneously flashing white or amber lights, or any shade of color between white and amber. The lamps used to display such warning to the rear shall be mounted at the same level and as widely spaced laterally as practicable, and shall show simultaneously flashing amber or red lights, or any shade of color between amber and red. These warning lights shall be visible from a distance of not less than 1,500 feet under normal atmospheric conditions at night.

Flashing lights may be used on motor vehicles as a means of indicating a right or left turn; a stop lamp may pulsate with different intensities provided that it meets at all intensities the provisions of subdivision (2) of subsection (b) of this section; and the warning lights on emergency vehicles may flash.
