IN THE UNITED STATES, LAMPS, REFLECTIVE DEVICES, AND ASSOCIATED EQUIPMENT ARE REGULATED BY THE US DEPARTMENT OF TRANSPORTATION (DOT) NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION’S FMVSS108 DOCUMENT. DOT / FMVSS108 APPLIES TO ALL VEHICLES USED ON PUBLIC STREETS IN THE UNITED STATES. DOT REGULATED PRODUCTS MUST COMPLY WITH DOT / FMVSS108 IN ORDER TO BE STREET LEGAL IN THE UNITED STATES. FOR EXAMPLE, HEADLIGHTS ARE REGULATED BY DOT / FMVSS108 AND MUST COMPLY WITH DOT / FMVSS108 TO BE STREET LEGAL IN THE USA. HOWEVER, FOG LIGHT BULBS ARE NOT REGULATED BY DOT / FMVSS108 AND ARE CONSIDERED STREET LEGAL IN THE USA.
Vehicle lighting bulbs are classified by ‘base fitment’ type, universally by OEM and aftermarket industry standards. Fitment does not confirm street legality in the USA. Street legality in the USA for retrofitting bulbs varies by both vehicle usage and light type. Bulbs are not available for purchase for illegal street usage. We recognize select vehicles could be used on public streets or off-street (not on public streets). Only vehicles which are strictly and 100% exclusively limited to off-street use qualify as off-street vehicles.
Mixed use (sometimes driven on public streets and sometimes driven off-street) vehicles do not qualify as off-street use vehicles. If a vehicle is driven on public streets whatsoever, even if just a little bit, the vehicle is not considered off-street use only. If your vehicle has registered license plates, it would not be considered off-street use only.
