Why Brake Light Maintenance is Crucial
Brake lights are an essential safety feature in your vehicle. They alert other drivers behind you that you’re slowing down or coming to a stop, allowing them to react accordingly. Faulty brake lights can lead to a range of consequences, including:

Rear-end collisions: If your brake lights aren’t functioning properly, other drivers may not be aware that you’re slowing down, leading to accidents.
-
Fines and penalties: In most jurisdictions, driving with faulty brake lights can result in fines and penalties.
-
Licence suspension: Repeated offenses can lead to license suspension, making it difficult to get to work, school, or other essential destinations.
-
Increased insurance premiums: A history of brake light-related accidents or fines can lead to increased insurance premiums.

Every 6-12 months as part of your regular vehicle maintenance schedule.
