About the headlights:

Your car’s headlights are vital to its safety and visibility when driving at night. Most modern cars have two front lights, which feature a high beam and low beam light and fog light. These different bulbs allow for different vision according to different conditions.

When your car’s headlights fail, the safety of the vehicle will be affected. This is because you won’t be able to see very well at night, and others will not be able to see you from a distance. For this reason, it is important to get your car’s headlights repairs as soon as possible. Damaged or broken headlights can also lead to your car failing its Warrant of fitness.

Causes of headlights not working:

  • Burned Out Bulbs: The most common cause of headlights not working is a burned-out bulb. Headlight bulbs have a limited lifespan, and over time, they can simply stop working. This is especially true for halogen bulbs, which tend to wear out more quickly than newer LED or HID bulbs.
  • Electrical Issues: Faulty electrical connections, wiring problems, or a blown fuse can result in headlights not functioning. If there is a loose or corroded connection, power may not reach the bulbs, preventing them from turning on. Checking the wiring, connectors, and fuse related to the headlights can help identify and resolve electrical issues.
  • Dimmer Switch or Control Module Failure: If both headlights fail to work, it could be due to a malfunctioning dimmer switch or control module. These components control the activation and intensity of the headlights. If they fail, it can result in the headlights not turning on or functioning properly.
  • Faulty Headlight Switch: The headlight switch, located on the dashboard, controls the operation of the headlights. If the switch becomes faulty or worn out, it may prevent the headlights from turning on. Testing the switch or replacing it may be necessary.
  • Bad Ground Connection: Headlights require a proper ground connection to function correctly. If the ground connection is damaged or corroded, it can disrupt the flow of electricity to the bulbs and cause the headlights to stop working.

Headlight replacement in Hamilton


When to replace headlights?

Are your car’s lights not turning on?

If your car’s headlights are not turning on at all, it is time to get the lights examined by a mechanic. Be sure to check your fuse box for a blown fuse. This is an easy fix and won’t require a bulb replacement.

Are your car’s headlights very dim?

Dim headlights can be the result of very old bulbs that are due for a replacement. Over time, the headlights will become dimmer until they do not provide an adequate view of the road anymore. This can affect your car’s safety or result in it failing its Warrant of Fitness. Dim headlights are not always caused by bad bulbs and can be a result of a corroded ground wire.

Are your car’s headlights blurry, fogged up, or oxidised?

Foggy headlights are a result of oxidisation occurring beneath the light’s protective cover. Foggy headlights can easily be fixed, meaning the bulb probably won’t need to be replaced. You can repair foggy headlights using household products such as toothpaste. Learn more.

It’s important to consult your vehicle’s manual or seek guidance from a trusted mechanic or automotive professional to determine the specific type and recommended replacement intervals for your headlights. Regularly inspecting your headlights and addressing any issues promptly will help ensure optimal visibility and safety while driving.


Is it time to upgrade to more modern bulbs?

If you want to enhance visibility or improve the appearance of your headlights, you may consider upgrading to more advanced and efficient bulb options, such as LED or HID bulbs. These bulbs often provide brighter and longer-lasting illumination, which can enhance safety and visibility on the road.
