Give yourself a better chance of staying safe this winter by upgrading your car’s headlights. Around £30 will buy you a pair of state-of-the-art bulbs which can dramatically improve your night vision, as well as reduce the risk of a collision. All the latest electronic in-car safety features – such as anti-lock braking, traction control and stability programmes – will count for little if you can’t see where you are going.

It’s important to fit the right bulb because, as our test shows again this year, buying anything but the top names is a lottery. Some cheap units produced worrying degrees of glare for oncoming drivers, as well as very low levels of light on the road and major differences between lamps.
