Why you should replace your bulbs in pairs

When one of your car bulbs fails, it can be tempting to just get that single bulb replaced. But there are several good reasons why you should always replace your bulbs in pairs.

It’s a time-saver

Bulbs tend to degrade at similar rates. This means that if one of your bulbs goes, chances are that the other one won’t be far behind. Replacing both bulbs at once means you avoid the hassle of having to take two trips to your local Halfords. You’ll also avoid the risk of being plunged into semi-darkness twice in a short space of time, which is not only inconvenient but also potentially dangerous.

It’ll give you consistent light quality

A new bulb shines more brightly than an old, worn out bulb. Different bulbs can also be different colours (particularly HID bulbs) and produce different amounts of light. So, if you only replace one bulb at a time then you’re always going to have uneven light quality. Driving at night already brings its own challenges, so why add another one to mix? Keep your beams balanced by replacing both bulbs at once.

It’ll help to make it safer for you – and other drivers

Uneven light doesn’t just affect you; it can affect other drivers too. We’ve all seen that car on the road, with one headlight that looks like it’s on full beam and the other barely on half. It’s distracting and can even be a little disorientating when you pass one another. Changing both of your bulbs at the same time can help to prevent this situation and make driving at night a little safer for everyone.

It’s a quick and easy process
