The term “are aftermarket headlights legal” refers to the legality of using headlights that are not the original equipment manufactured (OEM) headlights that came with a vehicle. Aftermarket headlights are typically purchased and installed by vehicle owners to replace the OEM headlights, often for aesthetic or performance reasons.
The legality of aftermarket headlights varies depending on the jurisdiction. In some areas, they are completely legal, while in others, they may be restricted or even prohibited. The primary concern with aftermarket headlights is that they may not meet the same safety standards as OEM headlights. For example, they may not provide adequate illumination or may cause glare for oncoming drivers.
