To avoid this, it's a good idea to complete a quick walk around once per week, before driving at night. It will also draw the attention of the police and most likely result in a "fix it ticket". This symptom can be very dangerous as a flickering light can be extremely distracting to other motorists on the road. This is commonly due to a loose wire or connection that powers the license plate light. However, in many cases, the license plate light will flicker. The license plate light is a solid light that is either on or off.
The license plate light is supposed to turn on when the headlights are activated including the main headlights or the parking light. Noted above are a few of the warning signs that an issue with your license plate light exists, so you can have the license plate light replaced by a mechanic if needed.
Like the rear brake and parking lights, there are several things any car owner can do to visually inspect the license plate light before they drive at night that can save you from receiving a traffic infraction ticket. To our knowledge, this technology does not include the license plate light.
Most of today's cars, trucks and SUV's have multiple sensors, monitoring devices and computers that relay information to the driver when a potential issue exists. However, since the license plate is displayed behind the vehicle you're driving, it's more likely that you won't know that a problem exists until it's too late and you've been pulled over by a police officer. This duty falls on the license plate light which is attached above the rear license plate frame and shines in a downward direction. According to the vehicle code in all US States, having the rear license plate efficiently illuminated at night is a requirement.
