What type of light is prohibited from showing at the front of a passenger vehicle in Texas?

In Texas, the law prohibits the display of red lights on the front of a passenger vehicle to prevent confusion with emergency vehicles. Red lights are typically associated with law enforcement, fire, and emergency services. Allowing red lights on the front of regular vehicles could mislead other drivers and create dangerous situations, as they might mistake the vehicle for an emergency response unit.

Other colors, such as white lights for headlights, blue lights which might be reserved for specific authorized vehicles, and yellow lights meant for signaling purposes in certain conditions, do not present the same issues of confusion or misrepresentation on the road as red lights do. Thus, prohibiting red lights at the front maintains clarity in roadside communication and improves overall traffic safety.
