The number plate light is an essential component of a vehicle that illuminates the number plate, making it visible in low light conditions. It is a legal requirement for all vehicles to have a working number plate light, and failure to comply can result in an MOT fail. In this article, we will explore the MOT fail number plate light and what you need to know to ensure your vehicle passes its MOT.
When it comes to the MOT test, the number plate light is one of the most common reasons for failure. A faulty or non-functioning number plate light can result in an instant fail, even if the rest of the vehicle is in good condition. This is because the number plate light is a crucial safety feature that allows other road users to identify your vehicle in low light conditions, such as at night or in bad weather.
If your vehicle fails its MOT due to a faulty number plate light, it is important to address the issue promptly. Not only is it a legal requirement to have a working number plate light, but it is also a safety concern. In the next section, we will discuss the common causes of number plate light failures and what you can do to prevent them.
Understanding MOT
When it comes to owning a vehicle, passing the MOT test is crucial. The MOT test is an annual inspection carried out by authorised garages to ensure that your vehicle meets the minimum safety standards set by the UK government.
During the MOT inspection, the tester will check a variety of components on your vehicle, including the number plate light. If the light is not working correctly, it will result in an MOT fail.
The number plate light is an essential component of your vehicle’s lighting system. It illuminates the rear number plate, making it visible to other road users in low light conditions. If the light is not working correctly, it can make it difficult for other road users to read your number plate, which can lead to safety issues.
To avoid an MOT fail due to a faulty number plate light, it’s essential to check it regularly. You can do this by turning on your vehicle’s lights and checking that the number plate light is working correctly. If it’s not, you can replace the bulb yourself or take it to a garage for repair.
In summary, passing the MOT test is essential for vehicle safety, and the number plate light is a crucial component in ensuring that your vehicle meets the minimum safety standards. Regularly checking and maintaining your number plate light can help you avoid an MOT fail and keep you and other road users safe on the road.
Legal Requirements for Number Plate Lights
We, as drivers, have a legal obligation to ensure that our number plate is clearly visible at all times. This not only applies during daylight hours but also during periods of darkness. To comply with this requirement, a number plate light must be fitted and in good working condition.
The legal requirements for number plate lights are set out in the Road Vehicles Lighting Regulations 1989. These regulations state that a number plate light must:
- Illuminate the number plate so that it can be read from a distance of 20 metres
- Emit a white light
- Be positioned centrally or offside, approximately 350mm from the ground
- Be protected from damage
It is worth noting that the regulations do not specify the type of bulb that should be used in a number plate light. However, we recommend using a bulb that complies with British Standard BS AU 148a. This will ensure that the light emitted is of the correct colour and intensity.
It is important to regularly check that your number plate light is in good working condition. If it is not working, it could result in an MOT failure. It is also worth noting that a defective number plate light could result in a fine and penalty points on your driving license.
In summary, to comply with legal requirements, a number plate light must illuminate the number plate so that it can be read from a distance of 20 metres, emit a white light, be positioned centrally or offside, approximately 350mm from the ground, and be protected from damage. Regularly checking that your number plate light is in good working condition is important to avoid an MOT failure and potential fines.
Common Reasons for Number Plate Light Failure
When it comes to the MOT test, one of the most common reasons for failure is a faulty number plate light. This may seem like a minor issue, but it is important to ensure that your number plate is clearly visible at all times, especially at night or in poor weather conditions. Here are some common reasons why number plate lights fail:
1. Bulb Failure
The most common reason for number plate light failure is a blown bulb. This can be caused by a number of factors, including age, vibration, and general wear and tear. It is important to check your number plate lights regularly and replace any blown bulbs as soon as possible.
