How many license plate lamps are required by law?

The law requires that at least one license plate lamp be installed on a vehicle to ensure that the license plate is adequately illuminated at night and under low visibility conditions. This requirement is in place to promote visibility and identification of vehicles, which is essential for law enforcement and traffic safety.

While having more than one lamp may enhance visibility, the legal requirement is satisfied with just one functioning lamp. This regulation ensures that all vehicles remain identifiable at all times while on the road, which is crucial for maintaining accurate records and upholding traffic laws. The focus here is on providing a minimal standard of compliance necessary for safe vehicle operation regarding identification, which is why one lamp is the legal requirement.
