I was doing online traffic school for disobeying a sign, and it said that underglow lighting is legal in california as long as it's not red and the light panel/tube is not visible. I looked into this more on google and this is what I found


V C Section 25400 Lighting Requirements
Lighting Requirements
25400. (a) Any vehicle may be equipped with a lamp or device on the exterior of the vehicle that emits a diffused nonglaring light of not more than 0.05 candela per square inch of area.

(b) Any diffused nonglaring light shall not display red to the front, but may display other colors. A diffused nonglaring light shall not resemble nor be installed within 12 inches or in such position as to interfere with the visibility or effectiveness of any required lamp, reflector, or other device upon the vehicle.

(c) A diffused nonglaring lamp or device, other than a display sign authorized by subdivision

(d), shall be limited in size to an area of 720 square inches and where any lease, rental, or donation is involved the installation of the lamp or device shall be limited to those vehicles operated either primarily within business or residential districts or municipalities, or between business districts, residential districts, and municipalities in close proximity.

(d) An internally illuminated sign emitting not more than 0.25 candela per square inch and possessing copy which does not contain a white background may be displayed on each side, but not on the front or rear, of a trolley coach or of a bus being operated in urban or suburban service as described in Section 35107 of this code.


Does this mean I can legally drive around with my neon lights under? If so I would be pretty happy. Does anyone have any input on this? Is it true? Or will they still find a way to fine me?

V.C. Section 25109
Running Lamps

25109. Any motor vehicle may be equipped with two white or amber running lamps mounted on the front, one at each side, which shall not be lighted during darkness except while the motor vehicle is parked.


V.C. Section 25950
Color of Lamps and Reflectors

25950. 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.

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

(5) The rearward facing portion of a front-mounted double-faced turn signal lamp may show amber to the rear while the headlamps or parking lamps are lighted, if the intensity of the light emitted is not greater than the parking lamps and the turn signal function is not impaired.

(6) A reflector meeting the requirements of and installed in accordance with Section 24611 shall be red or white, or both.

(c) All lamps and reflectors visible from the front, sides, or rear of a vehicle, except headlamps, may have any unlighted color, provided the emitted light from all lamps or reflected light from all reflectors complies with the required color. Except for backup lamps, the entire effective projected luminous area of lamps visible from the rear or mounted on the sides near the rear of a vehicle shall be covered by an inner lens of the required color when the unlighted color differs from the required emitted light color. Taillamps, stoplamps, and turn signal lamps that are visible to the rear may be white when unlighted on vehicles manufactured before January 1, 1974.


Underglow is NOT legal.

Its the running lamps law that gets you.

To fall under the diffused lighting law you would have to mount them within 12 inches of existing lighting or reflectors and because of opposing laws, you would be illegal.

Or you could just call a police dept and ask how much the fine for improper / illegal lighting is.

underglow is legal as long as it's used when parked.

tinting the taillings IS NOT illegal. In most states as long as you can see the light from a certain amount of feet. I think in Illinois light must be visible 500 ft away.

I was pretty sure they're illegal but I thought maybe I had some hope lol
Regardless they're still on there for whenever I see no cops :)

So I can sit parked next to a curb with them on and cops won't annoy me? :D

Tinting headlights is 100% illegal. Tail lights must shine from a certain distance(different in different states) and still have the ability to shine red and have reflectors. And they can still annoy you because it needs to be DOT approved. But from my experience, if your brake light is visible without problems they won't hassle you

They might still annoy you, but I don't think they can do anything about it. I had underglow on my old Integra and only got one ticket for it. It was from a state trooper who didn't like blue lights on a silver car. It got thrown out because I was parked legally on the side of the road. Not moving, no violation. As soon as I put the car in drive though, I turned them off. Its an ugly ticket in Michigan depending on color. Red and blue can get you a ticket for anything from improper lighting to impersonating a public official (blue = police and red = fire / EMS).

Just remember, a cop can write you a ticket if he wants. Doesn't mean it will stick in court. ;)

Underglow lighting is a serious crime... against good taste. :ph34r:

Haha yeah cops can write you tickets for anything, but I really doubt you'll win in court for having neon lights under your car lol. but if I do see a cop, i'll definitely turn them off, dont wanna risk it
