When should I replace my car’s headlights?

Having functioning car headlights is essential for a safe and comfortable driving experience. Over time, you may notice the headlight casing cracking or the bulbs flickering or dying, compromising your overall road safety. Discover when to replace your car’s headlights in our informative article.

The headlight bulbs are dead

Have you noticed when you turn your car’s headlights don’t illuminate the road? The bulbs on both sides of your headlights need to be replaced immediately. If your vehicle fails its MOT due to the headlights not working, our major repairs service will replace the bulbs in your headlights. Our headlight specialist will ensure your vehicle’s headlights continue illuminating the road whenever they are needed.

They flicker on and off

Occasionally, you might find your car’s headlights flicker on and off at random. Repeatedly using the headlights over an extended period can wear down the bulb’s filament, thus leading to the headlight failing. Alternatively, the headlights may flicker due to a faulty battery connection or defective cable harness. We recommend booking a car service at your nearest branch immediately where we can fix your vehicle’s flickering headlights.

They’ve become yellow or hazy

It’s common for car headlights to become yellow or have a hazy-like appearance. Salt, dirt, hot weather and UV rays can create a chemical reaction inside the headlight casing. When subjected to unfavourable conditions, such as excessively hot, sunny weather, the car’s headlight lenses will oxidise, creating a yellowed or cloudy appearance. Cloudy headlights can be restored with a specialised headlight cleaner. We also recommend parking in an area with plenty of shade, like a garage.

The bulbs are regularly burning out

Have you found your vehicle’s headlight bulbs are regularly burning out? This could indicate a fault with your car’s electrical system. The fuses can blow out due to faulty bulbs or because the bulbs have the incorrect wattage. Ensure you check the fuses, exposed wires in the harness, lighting switch and headlight assembly to find out where the issue is. If you cannot easily identify why your bulbs are blowing, contact your local branch and our specialist mechanic will fix it for you.

You have the wrong headlight bulbs for your vehicle

Headlight bulbs come in various sizes. Each model will require a different size and wattage of the bulb. If the incorrect bulb has been fitted, it will need to be replaced straight away to prevent the bulb from blowing. Refer to the owner’s manual to find out the correct specification for your vehicle.

Is your vehicle’s MOT due soon? Discover what pre-MOT checks you can carry out yourself, to improve the chances of your vehicle passing its MOT in our article. If the bulbs in your car’s headlights need replacing, visit your local Setyres branch across Southern England. If you have any questions about our services and the range of tyres we offer, contact our friendly team today.
