Headlights or headlamps?
Just to be clear, when we are talking about headlamps, we’re talking about the wider unit itself. This unit contains the bulbs (headlights) that light up the road ahead.
Both terms are sometimes used to describe one another. Sometimes you may see headlamps describing the light itself!
Tip: If you’re looking for replacement headlight bulbs for your vehicle, check from our blog which headlights you need for your car.
Now that we understand the key differences between headlights and headlamps, let’s find out how to know when you need to change them.
When to change your headlamp units
There is visible damage
If you notice any visible dents, cracks, or even holes in your headlamp casing, you should get these fixed as soon as possible. This may involve a replacement.
The protective casing helps to keep your headlight bulbs in a good, working condition. If the casing starts showing any signs of visible damage, this can’t be ignored.
Headlamp casings usually have a clear protective layer to prevent the acrylic from oxidising. This is another sign of deterioration we’ll come to next.
Some visible wear and tear may also occur over time with scratches and scrapes from debris on the road. Once this gets past the protective layer on your headlamp casing, it may cause the beam to become dimmer. This can result in poorer vision, which is a safety risk.
You notice they are turning yellow
Oxidisation means that the coating on your headlamps starts to wear off. This is often because of heat from UV rays, which can cause the casing to turn yellow.
This can happen during extreme, hot temperatures and if you regularly park your vehicle in direct way of sunlight.
It’s important not to ignore signs of oxidisation on your car’s headlamp casing. It can affect how the bulb’s light projection is reflected, making it look cloudier.
This can cause both poorer vision and a generally unattractive look for your vehicle - neither of which you want!
If this has been left unattended for a long time, your headlamp casing may need replacing entirely. You can avoid this by regularly washing your car and parking it in the shade if possible.
There are signs of water damage
Headlamp units usually have a water-tight seal to protect the bulbs from exposure to water. Over time, this seal can deteriorate from normal wear and tear.
This means that water can start to build up slowly inside the case, altering the quality of light coming out of your headlight bulbs. This often causes scattered beams of light.
If you notice any visible cracks or holes, it’s important to address these immediately. It could seriously impact the efficacy of your headlights and make your vehicle less safe.
