Title 3, Article 9, Section 375, Subsection 41 of the New York State
Vehicle and Traffic Law (NYSVTL) states:

§ 375. Equipment.
41. Colored and flashing lights.
The provisions of this subdivision shall govern the affixing and
display of lights on vehicles, other than those lights required by law.
1. No light, other than a white light, and no revolving, rotating,
flashing, oscillating or constantly moving white light shall be affixed
to, or displayed on any vehicle except as prescribed herein.
2. Red lights and certain white lights. One or more red or combination
red and white lights, or one white light which must be a
revolving, rotating, flashing, oscillating or constantly moving light, may
be affixed to an authorized emergency vehicle, and such lights may
be displayed on an authorized emergency vehicle when such vehicle
is engaged in an emergency operation, and upon a fire vehicle
while returning from an alarm of fire or other emergency.
3. Amber lights. a. One or more amber lights may be affixed to a
hazard vehicle, and such a light or lights which display an amber
light visible to all approaching traffic under normal atmospheric
conditions from a distance of five hundred feet from such vehicle
shall be displayed on a hazard vehicle when such vehicle is
engaged in a hazardous operation. Such light or lights shall not be
required to be displayed during daylight hours provided at least two red
flags visible from a distance of five hundred feet are placed both in or
on the front of, and to or on the rear of the vehicle and two such
flags are placed to each side of the vehicle open to traffic. Such
lights or flags need not be displayed on the vehicle when the
vehicle is operating, or parked, within a barricaded work area and said
lights or flags are displayed on the barricade. The provisions of
this subdivision shall not prohibit the temporary affixing and display of
an amber light to be used as a warning on a disabled motor vehicle or
on a motor vehicle while it is stopped on a highway while engaged in
an operation which would restrict, impede or interfere with the
normal flow of traffic.
b. In any city in this state having a population of one million or
more, one amber light may be affixed to any motor vehicle owned or
operated by a volunteer member of a civilian or crime patrol
provided such volunteer civilian or crime patrol member has been authorized
in writing to so affix an amber light by the police commissioner of
the municipality in which he patrols, which authorization shall be
subject to revocation at any time by the police commissioner who issued
the same or his successor in office. Such amber light may be
operated by such volunteer civilian or crime patrol member in such a vehicle
only when engaged in a patrol operation as defined and authorized
by rules and regulations promulgated by the police commissioner and
only in such a manner and at such times as may be authorized by the
police commissioner pursuant to said rules and regulations.
4. Blue light. a. One blue light may be affixed to any motor vehicle
owned by a volunteer member of a fire department or on a motor vehicle
owned by a member of such person's family residing in the same
household or by a business enterprise in which such person has a
proprietary interest or by which he or she is employed, provided such
volunteer firefighter has been authorized in writing to so affix a blue
light by the chief of the fire department or company of which he or
she is a member, which authorization shall be subject to revocation
at any time by the chief who issued the same or his or her successor in
office. Such blue light may be displayed exclusively by such volunteer
firefighter on such a vehicle only when engaged in an emergency
operation. The use of blue and red light combinations shall be
prohibited on all fire vehicles. The use of blue lights on fire vehicles
shall be prohibited and the use of blue lights on vehicles shall be
restricted for use only by a volunteer firefighter except as
otherwise provided for in subparagraph b of this paragraph.
b. In addition to the red and white lights authorized to be displayed
pursuant to paragraph two of this subdivision, one or more blue lights
or combination blue and red lights or combination blue, red and
white lights may be affixed to a police vehicle, provided that such blue
light or lights shall be displayed on a police vehicle for rear
projection only. In the event that the trunk or rear gate of a police
vehicle obstructs or diminishes the visibility of other emergency
lighting on such vehicle, a blue light may be affixed to and
displayed from the trunk, rear gate or interior of such vehicle. Such
lights may be displayed on a police vehicle when such vehicle
is engaged in an emergency operation. Nothing contained in this
subparagraph shall be deemed to authorize the use of blue lights on
police vehicles unless such vehicles also display one or more red or
combination red and white lights as otherwise authorized in this
subdivision.
c. The commissioner is authorized to promulgate rules and regulations
relating to the use, placement, power and display of blue lights on a
police vehicle.
5. Green light. One green light may be affixed to any motor vehicle
owned by a member of a volunteer ambulance service, or on a motor
vehicle owned by a member of such person's family, or by a
business enterprise in which such person has a proprietary interest or by
which he is employed, provided such member has been authorized in
writing to so affix a green light by the chief officer of such
service as designated by the members thereof. Such green light may be
displayed exclusively by such member of a volunteer ambulance service
only when engaged in an emergency operation. The use of green lights
on vehicles shall be restricted for use only by a member of a
volunteer ambulance service as provided for in this paragraph. As used in
this paragraph volunteer ambulance service means: a. a non-profit
membership corporation (other than a fire corporation) incorporated
under or subject to the provisions of the membership corporations
law, or any other law, operating its ambulance or ambulances
on a non-profit basis for the convenience of the members thereof
and their families or of the community or under a contract with a
county, city, town or village pursuant to section one hundred
twenty-two-b of the general municipal law; or b. an unincorporated
association of persons operating its ambulance or ambulances on a non-profit
basis for the convenience of the members and their families or of the
community.
6. The commissioner is authorized to promulgate regulations with
respect to the affixing and display of colored lights and to promulgate
specifications with respect to such lights.
7. The provisions of this subdivision forty-one shall not be
applicable to vehicles from other states or from the Dominion of Canada
which have entered this state to render police, fire or civil
defense aid, or ambulance service, while such vehicles are here or are
returning to their home stations if the lights on such vehicles comply with
the laws of their home states or the Dominion of Canada and are
displayed in this state in the same manner permitted by their home states
or the Dominion of Canada, nor shall the provisions of this
subdivision forty-one be deemed to amend, supersede or in any manner
affect the provisions of the New York state defense emergency act as
now in force or as it may be amended from time to time.
8. The provisions of this subdivision shall not be applicable to the
driver of a vehicle from another state or foreign jurisdiction which
vehicle has colored lights affixed but not revolving,
rotating, flashing, oscillating or constantly moving if the lights on such
vehicle comply with the laws of the state or home foreign jurisdiction in
which the vehicle is registered.

Therefore, according to the NYSVTL (i.e., Subsection 41([1]), it is not
legal to operate a motor vehicle in the State of New York with neon
lights (i.e., inside and/or outside).

Simply stated for New Jersey: other color lights (besides the usual colors for directionals and such) are illegal to have on while the vehicle is in motion. However once stationary, you can have all the lights and colors you want. A ticket even for the washer nozzles is a few hundred dollars. Definitely not worth the trouble.

If it's blue, it's probably illegal. Some states are lenient on other colors, but I think blue and red are illegal in every state.

§ 25950. Color of lamps and reflectors; Exceptions

This section applies to the color of lamps and to any reflector exhibiting or reflecting perceptible light of 0.05 candela or more per foot-candle of incident illumination. Unless provided otherwise, the color of lamps and reflectors upon a vehicle shall be as follows:

(a) The emitted light from all lamps and the reflected light from all reflectors, visible from in front of a vehicle, shall be white or yellow, except as follows:

(1) Rear side marker lamps required by Section 25100 may show red to the front.

(2) The color of foglamps described in Section 24403 may be in the color spectrum from white to yellow.

(3) An illuminating device, as permitted under Section 24255, shall emit radiation predominantly in the infrared region of the electromagnetic spectrum. Any incidental visible light projecting to the front of the vehicle shall be predominantly yellow to white. Any incidental visible light projecting to the rear of the vehicle shall be predominantly red. Any incidental visible light from an illuminating device, as permitted under Section 24255, shall not resemble any other required or permitted lighting device or official traffic control device.

( The emitted light from all lamps and the reflected light from all reflectors, visible from the rear of a vehicle, shall be red except as follows:

(1) Stoplamps on vehicles manufactured before January 1, 1979, may show yellow to the rear.

(2) Turn signal lamps may show yellow to the rear.

(3) Front side marker lamps required by Section 25100 may show yellow to the rear.

(4) Backup lamps shall show white to the rear.

Maryland

2 - ILLEGALLY COLORED LIGHTS - Another violation which seems to be in abundance lately is vehicles with lights or lenses
which are in violation of the Maryland Vehicle Law. Officers are routinely stopping vehicles with Blue, Green and Purple
lights added to/or mounted in lieu of, the vehicle's original lights. (The small "laser" lights mounted to the hood are the most
common violation.) We're also finding many people who have removed the Red Lenses and Reflectors from the tail lights
of their cars, and installed CLEAR lenses instead. (Clear lenses are legal only if the bulbs themselves are still located
behind RED plastic, and the required minimum amount of RED Reflecting Material is installed in the clear lenses.)

The Maryland Vehicle Law clearly states the colors which are required on the front, back and sides of vehicles used on
public highways, and these laws are in conformance with the Federal Safety Standards for Motor Vehicles
manufactured in the United States. Changing or altering these required items subjects the vehicle operator to a
Moving Vehicle Traffic Citation, (usually $40-50) and/or a Safety Equipment Repair Order.

Again, be forwarned that just because a product is sold in a retail store like Trak Auto, Pep Boys, etc., that does not mean
that it is legal to use it. Most "after-market" vehicle products have a small disclaimer listed somewhere on the box or
package, which reads: "NOT FOR HIGHWAY USE," or "CHECK LOCAL LAWS BEFORE USING THIS PRODUCT."
The manufacturers of these products do this to place the responsibility for using their merchandise on YOU.
Even if a disclaimer is not listed on a particular item, the responsibility is still on the owner or operator of the vehicle
to make sure that it complies with the law when used on the public highways of the state.

Additionally, Maryland law requires that any after market device sold must be approved by the Administrator of
the Department of Motor Vehicles, before it can be installed on a vehicle. The small "Laser" Lights mounted on the hood,
Neon Tubes mounted under the vehicle which give a "glowing" effect, and many of these other "auto parts store" items
have NOT been approved for use on vehicles in Maryland.

WHEN IN DOUBT ABOUT A PARTICULAR AFTER-MARKET ITEM, CONTACT THE MARYLAND STATE POLICE -
AUTOMOTIVE SAFETY ENFORCEMENT DIVISION AT (410) 424-3787 FOR AN OFFICIAL RULING.
SAVE YOURSELF UNECESSARY FINES, POINTS OR IMPOUNDMENT OF YOUR VEHICLE!

Tennessee!

I have lived in Tennessee for almost my whole life. I have had Green turn signals up front for over 5 years. No law enforcement has pulled me over for them. I now also have the black led washer lights (GREEN); and nothing has become of it. My GREEN LED undercar kit is not installed, but I see plenty of tractor-trailers and motorcycles with other color lights (auxilary/secondary/accessoy) and they are not stopped or ticketed.

In Tennessee and some other states, it is the officer's choice and opinion to stop and ticket on the basis of "dazzling and/or confusing". I think this is a loop hole in the law and we are the blunt end of the 'ticket-quota' stick! Remember, a law officer is to 'protect and serve' you; not only government. If they say it is against the law to have neons, politely ask them for a reference to where the law is written or document for further reference and education. Usually; they will not answer this and get frustrated. If/When ticketed, your defense is that the officer could not provide reference or public record of the offense in question. Always be polite and respectful; law enforcement usually and most likely has a power complex. Best of Luck!

I have been researching the statutes for Arkansas and have found nothing specifically forbidding running underglow (while driving or otherwise). BUT was told by a local cop that a ticket for driving with them on would be for faulty equipment.

Even the section on lighting restrictions only forbids red, blue, and green, but that's it.

So if my state law doesn't prohibit it, that doesn't mean that my county/city law doesn't, meaning even if my state doesn't say it's illegal, it may still be in my area, is this correct?
