If you have some official local gov or state gov docs that show the legality or illegality of these lights, please post them.
Thanks.

NHTSA Notice: Glare from Headlamps and other Front Mounted Lamps - FMVSS 108
"Another disturbing trend in this look-a-like phenomenon is the substitution of OEM filament headlamp bulbs with aftermarket HID conversion bulbs. The desire is to achieve the look and achieve the more robust performance of HIDs. While not designed to be interchangeable, some aftermarket companies are substantially altering the HID bulb bases or providing adapters so that the HID bulbs can be inserted in headlamps designed for filament bulbs. The consequence of making these substitutions is to adversely affect safety. Filament headlamps are optically designed for the volume of light and filament placement and other critical dimensions and performance that OEM filament bulbs have. The HID conversions result in two to three times the volume of light and potentially imprecise arc placement. Such conversions often result in beam patterns that behave nothing like the original filament beam pattern, cannot be reliably aimed, and have many times the permitted glare intensity. In informal conversations with persons who have tested such conversions, the light intensity on one at a point aimed toward oncoming drivers was 22 times the allowable intensity limit. Another lamp was more than 7 times too intense. With poor HID bulb and arc placement, the glare intensity could be significantly worse. Thus, the use of these conversions could be yet another source of the glare problems about which many drivers have complained.
Regarding bluer light achieved by these filament bulbs, recent research (Sullivan, J.M. and Flannagan, M.J.: AVisual Effects of Blue-Tinted Tungsten-Halogen Headlamp Bulbs", Report No. UMTRI-2001-9, available in Docket: NHTSA-2001-8885-2) shows consistency with prior research, that discomfort glare ratings increase as the chromaticity moves toward the blue color range of the visible light spectrum. The authors also state that there is no evidence to show that target detection is enhanced with such blue colored headlamps, either in direct viewing or peripheral viewing of illuminated targets. This, essentially, shows that there likely is an inherent disbenefit from the use of such blue bulbs and headlamps that are intended to change the color of light emitted from headlamps. While one might assume that this also applies to the bluer HID powered OEM headlamps, the authors did not study this, nor speculate about it."
If you live in California, CHP will ticket you under California Vehicle Code 26101.
In black and white.....
V.C. Section 26101 - Modification of Vehicle Equipment
Technically, retrofits of oem hid projectors into other housings are illegal as well as the DOT/SAE certification is no longer valid, but it eliminates the glare that is the entire reason for the law and NHTSA study.
This is not to slam the group buy, just meant to educate....People will do whatever they want regardless of the legality or what I say......
