When Should your Car’s Headlight Bulbs be Changed?

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:

  • Blown bulb – Eventually, your car’s headlight bulbs will fail. This will result in the light not working at all.
  • Faulty wiring  – Sometimes, the wiring that links your lights to the battery will become damaged. This will sever the circuit and prevent the light from working.
  • Blown fuse – Your car uses a set of fuses to prevent damage to wiring or circuits. If the fuse blows, no power will reach your car’s light until it is replaced.

Headlight replacement in Hamilton


When to replace headlights?

Are your car’s lights are 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.
