  • Number of allowable headlights, fog lights, driving lights...?

    I've read that many states have specific code to limit vehicles from driving in non-fog weather with the fog lights on. Other than the code that talks about glaring lights I can't see any code that would limit drivers from needless use of fog lighting.

    Well since there are so many diffrent kinds of aux. lighting systems available I just use my own judgement as to whether they are too much to use on the highway. A few companies make driving lights that are acceptable to use but there again if the person doesn't have them adjusted properly they will be glaring. Give them a light show of your own if you pass one and it feels like you just looked into the sun! I personally do not care how many lights a vehicle has as long as its not too bright. Look at new luxury car those HID lights are very blinding on some of them but they are OEM and legal.

      It's very easy to do a search for Ga law and look this up.

      40-8-29. Spotlights, foglights, and auxiliary lights permitted.

      Statute text
      (a) Any motor vehicle may be equipped with not to exceed one spotlight, and no lighted spotlight shall be aimed and used upon any approaching vehicle. It shall be unlawful for any person except law enforcement officers and persons licensed under Chapter 38 of Title 43 to operate a spotlight from any moving vehicle on any highway or public roadway.
      (b) Any motor vehicle may be equipped with not to exceed two foglights mounted on the front at a height not less than 12 inches nor more than 30 inches above the level surface upon which the vehicle stands and so aimed that when the vehicle is not loaded none of the high intensity portion of the light to the left of the center of the vehicle shall at a distance of 25 feet ahead project higher than a level of four inches below the level of the center of the light from which it comes.
      (c) Any motor vehicle may be equipped with not to exceed one auxiliary passing light mounted on the front at a height not less than 24 inches nor more than 42 inches above the level surface upon which the vehicle stands, and every such auxiliary passing light shall meet the requirements and limitations set forth in this article.
      (d) Any motor vehicle may be equipped with not to exceed one auxiliary driving light mounted on the front at a height not less than 16 inches nor more than 42 inches above the level surface upon which the vehicle stands, and every such auxiliary driving light shall meet the requirements and limitations set forth in this article.
      Here is how they need to be set up

      40-8-30. Standards for multiple-beam road lighting equipment.

      Statute text
      Except as hereinafter provided in this part, the headlights or the auxiliary driving light or the auxiliary passing light or combination thereof on motor vehicles other than motorcycles or motor driven cycles shall be so arranged that the driver may select at will between distributions of light projected to different elevations, and such lights may, in addition, be so arranged that such selection can be made automatically, subject to the following limitations:

      (1) There shall be an uppermost distribution of light, or composite beam, so aimed and of such intensity as to reveal persons and vehicles at a distance of at least 350 feet ahead for all conditions of loading;
      (2) There shall be a lowermost distribution of light, or composite beam, so aimed and of sufficient intensity to reveal persons and vehicles at a distance of at least 100 feet ahead; and on a straight level road under any condition of loading none of the high intensity portion of the beam shall be directed to strike the eyes of an approaching driver;
      (3) Every new motor vehicle other than a motorcycle or a motor driven cycle registered in this state which has multiple-beam road lighting equipment shall be equipped with a beam indicator which shall be lighted whenever the uppermost distribution of light from the headlights is in use and shall not otherwise be lighted. Such indicator shall be so designed and located that when lighted it will be readily visible without glare to the driver of the vehicle so equipped.
      The bottom line is it can't blind on coming traffic. It also has to have an indicator light inside the vehicle that lets the driver know he has his high intensity lights on, like the hi-beam indicator on all vehicles.

      It's your judgement. If the fog lights are blinding they get a ticket, unless they made an effort to turn them off as you approached.

      The vehicle can have 1 driving light and 1 passing light, in addition to the normal lights and 2 fog lights.

      None of the lights can be mounted on the top of the truck like you see some of these "off road" vehicles have. That would be a violation of the height standard for lighting. I see many trucks with these but they have them covered and only use them when they go off road.

        "85W of light from only a 55W power draw! With PIAA's H3 , the 1100X driving lights produce a highly focused beam that penetrate far into the darkness."

        None of the lights can be mounted on the top of the truck like you see some of these "off road" vehicles have.
        Now this jeep would be easy as it cleary violates the height limits, though I have never witnessed one with the lights on while on the road. But I count 6 extra lights.



        none of the high intensity portion of the beam shall be directed to strike the eyes of an approaching driver;
        Which applies to low beams. Or can that be applied to fog, auxiliary and passing lights. Perhaps the officer would have to pace out 100 feet and see if that light source illuminates "of sufficient intensity to reveal persons"

            S5.5.11(a) Any pair of lamps on the front of a passenger car, multipurpose passenger vehicle, truck, or bus, whether or not required by this standard, other than parking lamps or fog lamps, may be wired to be automatically activated, as determined by the manufacturer of the vehicle, in a steady burning state as daytime running lamps (DRLs) and to be automatically deactivated when the headlamp control is in any ``on'' position, and as otherwise determined by the manufacturer of the vehicle.

            (2) Is permanently marked ‘‘DRL’’ on its lens in letters not less than 3 mm high, unless it is optically combined with a headlamp; I'd bet that those LED light strips are not marked DRL

            (3) Is designed to provide the same color as the other lamp in the pair, and
            that is one of the following colors as defined in SAE Standard J578 MAY88:
            White, white to yellow, white to selective yellow, selective yellow, or yellow; blue is not allowed by Federal or Georgia code

            (4) If not optically combined with a turn signal lamp, is located so that the
            distance from its lighted edge to the optical center of the nearest turn signal
            lamp is not less than 100 mm, unless: (iv) The DRL is deactivated when the
            turn signal or hazard warning signal lamp is activated.

            S6.5.1.2 Each original equipment or replacement lamp or reflective device specified in Table I, except for a headlamp, or an item of associated equipment specified in S9 may be marked with the symbol ‘‘DOT’’ which constitutes a certification that it conforms to the requirements of this standard.

            Now the federal code does allow front parking lamps to be amber or white DOT approved bulbs and mounted not less than 16" So a vehicle might get away with such lighting if it meets the code requirements to be used as parking lamps..

            (a) When the parking lamps are activated, the taillamps, license plate lamps, and side marker lamps shall also be activated;

              U.S. Department 400 Seventh St S W
              of Transportation Washington, DC 20590
              National Highway
              Traffic Safety
              Administration April 14, 1998


              The requirements for headlamps on new motor vehicles intended to be sold to the public for use on highways are specified in Federal Motor Vehicle Safety Standard No. 108, "Lamps, reflective devices and associated equipment, " (the Standard). This Standard applies to lighting
              for new motor vehicles, to lighting equipment intended to replace required lighting on motor vehicles in-use, and to certain items of specified new lighting equipment that may not be supplied as original equipment on new motor vehicles.
              The color of light emitted by headlamps is required to be white. The boundaries of white specified by the Standard are relatively wide; thus, when referring to the specified boundaries as plotted on the CIE 1931 2° Chromaticity Diagram, it can be seen that white may have high
              content of yellow, red, purple, blue, or green, depending on the measured chromaticity coordinates of the emitted light and its location relative to the defined boundaries for the color white. The color of a headlamp is usually measured in the central portion of the beam pattern, where there is little optical bending to form the beam. Measurements taken toward the edges
              of the beam pattern can result in incorrect color measurement because of light reflection that occurs in the elements of the lamp's optics. This reflection can cause separation of the light's constituent wavelengths, and often blue and red colors can be observed. This occurs regardless of the type and nature of the light source used by the headlamp. If the beam has obvious coloration at places other than at its edges, then color tests are done in locations chosen by the test technician where the measurement of colors outside the CIE white boundaries are judged to be likely. The color test is not performed on the bulb alone. Thus, casual observation of headlamps may seem to show that the lamp is emitting light that is
              not white. This does not necessarily mean that the headlamp does not comply with the Standard's requirement that it emit white light. When observing a beam projected on a white screen, headlamps that comply will have the projection be obviously white with color separations occurring only at the extreme edges of the pattern.


              The agency has not found any original equipment headlamps out of compliance with the color requirement, nor does the agency have any reason to believe that any headlamps on new motor vehicles would fail to comply with the color requirement if they were to be tested.

              the agency is aware that certain replacement headlamp light sources
              (bulbs) that are claimed not to be intended for use by highway motor vehicles, may emit colors that if tested might not comply with the Standard's color requirements. The agency has not tested any of these bulbs and may not likely test any, if the bulbs are not certified as being intended to replace complying motor vehicle equipment. These bulbs, if not certified to comply
              with the Standard, are not permitted to be installed on new motor vehicles to be sold to the public and are not permitted to be installed in any highway motor vehicle by any party regulated by NHTSA. Thus, vehicle and vehicle equipment manufacturers, dealers and persons in the business of repairing motor vehicles are prohibited from installing such bulbs in motor vehicles Vehicle owners are not regulated parties, and are not prohibited by federal law from installing such bulbs. However, if local or[B]
              This is a very good 5 page letter. http://www.aamva.org/aamva/DocumentDisplay.aspx?id={A5FD8E7E-DA6D-46BD-A71D-109EE1A1A121}

                Federal code also details that those non-factor aftermarket fog light, accessory lights, driving lights must be wired in with the factory wiring harness. A second switch is not allowed. The fog lights must be wired in so that when the driver selects high beams the fogs switch off. Or if the car is equipped with a higher powered driving light it must indicate high beam status on the dash and work in conjunction with the high low beam factory switch.


                S5.5.9 Except as provided in section S5.5.8, the wiring harness or
                connector assembly of each headlamp system shall be designed so that
                only those light sources intended for meeting lower beam photometrics
                are energized when the beam selector switch is in the lower beam
                position, and that only those light sources intended for meeting upper
                beam photometrics are energized when the beam selector switch is in the
                upper beam position.

                  "Manufacturers are required to certify motor vehicle lighting equipment using bulbs which meet SAE specifications. Since there is currently no SAE specification for a red bulb, a red bulb could not be used to show conformance with SAE standards. Therefore, no taillamp with an all clear lens could possibly comply with the red color requirements specified in S5.1.5 of the standard.

                  Furthermore, NHTSA knows of no manufacturer who is producing a red bulb that is intended to make signal lamps with colorless lenses comply with FMVSS No. 108 (see interp). "

                    The lights you have posted above are the new Audi style lights. They are ment to be daytime running/parking light hybrids. As far as I know they are legal in all 50 states. Also the Night photo you have is just with the hybrid lights on not both them and the headlights.

                      Nope. Those are non-original aftermarket lights for a Honda Civic. If they are DRL then they must be wired in as the federal code says.

                      "S5.5.11(a) Any pair of lamps on the front of a passenger car, multipurpose passenger vehicle, truck, or bus, whether or not required by this standard, other than parking lamps or fog lamps, may be wired to be automatically activated, as determined by the manufacturer of the vehicle, in a steady burning state as daytime running lamps (DRLs) and to be automatically deactivated when the headlamp control is in any ``on'' position, and as otherwise determined by the manufacturer of the vehicle."

                      Also those aftermarket lights emit a near solid blue color.

                      Plus the aftermarket lights must satisfy DOT and SAE labeling. As well as correct color and light output for turn signals and parking lamps. It is a safe bet that those lamps I post a picture fail and least one if not several code sections.


                      Compare factory Audi to aftermarket junk for the Civic

                      aftermarket Honda Civic


                      Can you tell which is factory and which is aftermarket?

                      -

                      -


                      This is a LED light strip that can be taped onto the car to imitate the Audi DRL look. Now these are sorta grey area to me. They are not legal by several codes sections. But the problem is that people tend to push the limit as you will see in this next photo.


                      Sold as a 12 LED JDM city lamp in white or as pictured ultra blue

                        I didnt say the were Audi lights, I said Audi style lights. I see your point but the photos above of the Audi vs. Honda doesn't show how the Audi lights really look. They were taken in a studio using special lighting and flash shades to show detail. Go down to the Audi dealer and look at those lights in person they are just as bright as th Honda's aftermarket lights. But the last pic above I do agree is too far and would be put on the shoulder. In reality there are thousands of aftermarket lights some legal some not. So thats why I say use your own judgement as to when its to much. Aftermarket lighting is such a grey area as to the way they are made and the way laws are written.

                          The Audi style lights is not all about brightness. It is about having the wrong color and not being properly wired to turn off when headlights and/or interfering with turn signals.

                            My state authorizes four forward-facing lights to be on at any one time. Two of which must be OEM headlights. Auxiliary lights may not be on if they are mounted higher than the OEM headlights.
                            I am concerned for the security of our great Nation; not so much because of any threat from without, but because of the insidious forces working from within.
