Why did your car’s lights cause it to fail a Warrant of Fitness?

A working set of lights is vital to the safety and visibility of your vehicle, especially at night. It is important that lights are replaced when they break. This is done to prevent accidents and from occurring due to reduced visibility. Below are some of the most important lights that should be working correctly to pass a Warrant of Fitness.

  • Headlights
  • High-beam lights
  • Brake lights
  • Indicator (turn signal) lights
  • Reversing lights

Headlights and high beams:

Your headlights and high beams allow you to see the road in front of you. They also alert other drivers that you are coming towards them. Over time, the bulbs inside headlights can lose their brightness. The area surrounding the bulbs can also become foggy due to oxidisation. When these problems occur, the headlight bay need to be replaced in order to pass a Warrant of Fitness. Common causes of failed Warrant of Fitnesses for headlights include:

  • One or more bulb not working
  • The blubs are not giving off enough light
  • The headlights aiming too low and needing adjustment
  • Physical damage has occurred, leading to cracks, holes or other damage.

Brake lights:New brake lights Waikato

Your brake lights (or stop lights) activate when the brakes are applied and your car is slowing down. This allows surrounding traffic to adjust their following distance. Problems with the brake lights can increase the risk of accidents, due to the cars behind you not knowing you are stopping. Common reasons for brake lights to fail their Warrant of Fitness include:

  • One or more bulbs blown or not producing light
  • Faulty wiring between the brakes and brake lights, causing them to not always activate.
  • Cracks, holes or other damage to the brake light

It is important to occasionally check the functionality of your brake lights. This is because when they stop working, you may not notice.
