How many license plate lamps are required to be functional?

The requirement for license plate lamps is that there must be at least one functional lamp. This regulation ensures that the license plate is illuminated properly for visibility and identification, especially during nighttime or low-light conditions. Having at least one working lamp is sufficient to ensure compliance with safety and visibility standards established by vehicle inspection regulations.

While there may be instances where vehicles could have two or more lamps, the definitive legal requirement is that at least one must be operational. This minimal requirement is designed to enhance safety without demanding unnecessarily complex or redundant systems for illumination.
