A license plate light illuminates the rear license plate of a vehicle, making it visible to other drivers, especially at night or in low-visibility conditions. It is a legal requirement in most jurisdictions to have a functioning license plate light, as it helps identify the vehicle and its owner in case of an accident or traffic violation.
Besides its legal importance, a license plate light also offers practical benefits. It enhances road safety by making it easier for other drivers to see and identify your vehicle, reducing the risk of rear-end collisions and other accidents. Moreover, a well-lit license plate can deter potential criminals or help law enforcement identify a vehicle involved in a crime.
