Smoked headlights are standard white headlights with screens or other tinting materials applied to obtain a dimmed headlight effect. The Pennsylvania Code contains the statutes that govern the required equipment on motor vehicles, including headlights. While headlight screens may be sold in stores, the Pennsylvania Code specifically prohibits their use while operating any type of motor vehicle. They may be used for display purposes or off-road driving only.
Section 175.66 of the Pennsylvania Code states that the headlights on passenger vehicles, motorcycles and small trucks must be white and meet a minimum level of brightness. Part (g) of this section states the lamps must be white and "not be so obstructed by a screen, bar, auxiliary equipment or a device as to obscure, change the color of or obstruct beam." This includes smoked headlight screens or materials.
Section 175.80 states that any motor vehicle equipped with a screen or other material that changes the color or dims the beam of the front headlights will fail inspection. Passing inspection is required by Pennsylvania law for a vehicle to be operated on public roads within the state. Violation of these statutes is a traffic infraction that could result in the vehicle being towed.
The Pennsylvania Code specifies that vehicles equipped with smoked headlights will not pass inspection and may not be operated on public roads; however, there are no laws prohibiting their use for display purposes or off-road use. As long as they are removed before the vehicle is operated on a public road, they may be used.
