Here are the FDOT laws regarding HID lighting for headlights. In summary, they need to:
1) be in housings designed for HID capsules
2) be very easy to aim
3) it must be hard to alter the aim by mistake
The fine for violating this FDOT law is $10,000 ---- that's why the seller states "for offroad use only" on these "kits".
(e) If a ballast is required for operation, each ballast shall bear the following permanent markings:
(1) Name or logo of ballast manufacturer;
(2) Ballast part number or unique identification;
(3) Part number or other unique identification of the light source for which the ballast is designed;
(4) Rated laboratory life of the light source/ballast combination, if the information for the light source has been filed in Appendix B of part 564 of this chapter;
(5) A warning that ballast output voltage presents the potential for severe electrical shock that could lead to permanent injury or death;
(6) Ballast output power in watts and output voltage in rms volts AC or DC; and
(7) The symbol `DOT'.''
(f) For light sources that use excited gas mixtures as a filament or discharge arc, the ``rated laboratory life'' shall be determined in accordance with sections 4.3 and 4.9 of SAE Recommended Practice J2009 FEB93 Forward Discharge Lighting Systems.
S7.8 Aimability Performance Requirements.
S7.8.1 (a) Each headlamp or beam contributor that is not visually/optically aimable in accordance with S184.108.40.206 of this standard shall be equipped with fiducial marks, aiming pads, or similar references of sufficient detail and accuracy, for determination of an appropriate vehicle plane to be used with the photometric procedures of SAE J1383 APR85 for correct alignment with the photometer axis when being tested for photometric compliance, and to serve for the aiming reference when the headlamp or beam contributor is installed on a motor vehicle. The fiducial marks, aiming pads, or similar references are protrusions, bubble vials, holes, indentations, ridges, scribed lines, or other readily identifiable marks established and described by the vehicle or headlamp manufacturer.
(b) Each motor vehicle manufactured on and after September 1, 1998, shall be equipped with headlamps or beam contributors which have a mark or markings that are visible from the front of the headlamp when installed on the vehicle to identify the optical axis of the headlamp to assure proper horizontal and vertical alignment of the aiming screen or optical aiming equipment. The manufacturer is free to choose the design of the mark or markings. The mark or markings may be on the interior or exterior of the lens or indicated by a mark or central structure on the interior or exterior of the headlamp.
(c) Each headlamp that is visually/optically aimable in accordance with S220.127.116.11 of this standard shall be marked in accordance with S18.104.22.168(f).
S7.8.2 Except as provided in this paragraph, each headlamp shall be installed on a motor vehicle with a mounting and aiming mechanism that allows aim inspection and adjustment of both vertical and horizontal aim, and is accessible for those purposes without removal of any vehicle parts, except for protective covers removable without the use of tools.
(c) A visually/optically aimable headlamp that has a lower beam shall not have a horizontal adjustment mechanism unless such mechanism meets the requirements of paragraph S22.214.171.124 of this standard.
(b) Conform with the photometrics applicable to it with the lens at any position relative to the reflector within the range limits as specified in S126.96.36.199(a)
S7.8.5 When activated in a steady-burning state, headlamps shall not have any styling ornament or other feature, such as a translucent cover or grill, in front of the lens. Headlamp wipers may be used in front of the lens provided that the headlamp system is designed to conform with all applicable photometric requirements with the wiper stopped in any position in front of the lens. When a headlamp system is installed on a motor vehicle, it shall be aimable with at least one of the following: An externally applied aiming device, as specified in S188.8.131.52; an on-vehicle headlamp aiming device installed by the vehicle or lamp manufacturer, as specified in S184.108.40.206; or by visual/optical means, as specified in S220.127.116.11.
S18.104.22.168 External aiming. Each headlamp system that is capable of being mechanically aimed by externally applied headlamp aiming devices shall be mechanically aimable using the equipment specified in SAE Standard J602 OCT80 Headlamp Aiming Device for Mechanically Aimable Sealed Beam Headlamp Units without the removal of any ornamental trim rings, covers, wipers or other vehicle parts.
(b) When a headlamp is installed on a motor vehicle, its aim in any
direction shall not change by more than 0.30 degree nor shall the lamp recede more than 0.1 in. (2.5 mm.) after being subjected to an inward
force of 50 pounds (222 newtons) applied evenly to the lens parallel to the mechanical axis.
S22.214.171.124 On-vehicle aiming. Each headlamp system that is capable of being aimed by equipment installed on the vehicle shall include a Vehicle Headlamp Aiming Device (VHAD) that conforms to the following requirements:
(a) Aim. The VHAD shall provide for headlamp aim inspection and adjustment in both the vertical and horizontal axes.
(1) Vertical aim. The VHAD shall include the necessary references and scales relative to the horizontal plane to assure correct vertical aim for photometry and aiming purposes. An off-vehicle measurement of the angle of the plane of the ground is permitted. In addition, an equal number of graduations from the ``O'' position representing angular changes in the axis in the upward and downward directions shall be provided.
(i) Each graduation shall represent a change in the vertical
position of the mechanical axis not larger than 0.19 degree (1 in. at 25 ft.) to provide for variations in aim at least 1.2 degrees above and below the horizontal, and have an accuracy relative to the zero mark of less than 0.1 degree.
(ii) The VHAD shall be marked to indicate headlamp aim movement in the upward and downward directions.
(iii) Each graduation shall indicate a linear movement of the scale indicator of not less than 0.05 in. (1.27 mm) if a direct reading analog indicator is used. If a remote reading indicator is provided, it shall represent the actual aim movement in a clear, understandable format.
(iv) The vertical indicator shall perform through a minimum range of +/-1.2 degrees.
(v) Means shall be provided in the VHAD for compensating for deviations in floor slope less than 1.2 degrees from the horizontal that would affect the correct positioning of the headlamp for vertical aim.
(vi) The graduations shall be legible under an illumination level not greater than 30 foot candles, measured at the top of the graduation, by an observer having 20/20 vision (Snellen), and shall permit aim adjustment to within 0.19 degree (1 in. at 25 ft.).
(2) Horizontal aim. The VHAD shall include references and scales relative to the longitudinal axis of the vehicle necessary to assure correct horizontal aim for photometry and aiming purposes. An ``O'' mark shall be used to indicate alignment of the headlamps relative to the longitudinal axis of the vehicle. In addition, an equal number of graduations from the ``O'' position representing equal angular changes in the axis relative to the vehicle axis shall be provided.
(i) Each graduation shall represent a change in the horizontal position of the mechanical axis not greater than 0.38 degree (2 in. at 25 ft.) to provide for variations in aim at least 0.76 degree (4 in. at 25 ft.) to the left and right of the longitudinal axis of the vehicle, and shall have an accuracy relative to the zero mark of less than 0.1 degree.
(ii) The VHAD shall be marked to indicate headlamp aim movement in the left and right directions.
(iii) The graduations shall be legible under an illumination level not greater than 30 foot candles, measured at the top of the graduation, by an observer having 20/20 vision (Snellen), and shall permit aim adjustment to within 0.38 degree (2 in. at 25 ft.).
(iv) The horizontal indicator shall perform through a minimum range of +/-0.76 degree (4 in. at 25 ft.); however, the indicator itself shall be capable of recalibration over a movement of +/-2.5 degrees relative to the longitudinal axis of the vehicle to accommodate any adjustment necessary for recalibrating the indicator after vehicle repair from accident damage.
(b) Aiming instructions.
(1) The instructions for properly aiming the headlighting system using the VHAD shall be provided on a label permanently affixed to the vehicle adjacent to the VHAD, or in the vehicle operator's manual. The instructions shall advise that the headlighting system is properly aimed if the appropriate vertical plane (as defined by the vehicle manufacturer) is perpendicular to both the longitudinal axis of the vehicle, and a horizontal plane when the vehicle is on a horizontal surface, and the VHAD is set at ``O'' vertical and ``O'' horizontal.
