What do dashboard warning lights mean?

Dashboard warning lights are great at updating you on your car's health, but they can sometimes be confusing...

  • A red warning light typically means that your car needs urgent attention.
  • A brake or temperature warning light means it may be time to contact your breakdown cover provider.
  • Amber or yellow dashboard lights suggest something's off but not urgent.

Dashboard lights can cause distractions on the road and impact our ability to drive safely. That's why it's important you know which action to take when your dashboard does light up.

What do the colours on your dashboard mean?

Just like a traffic light, the colours on your dashboard mean different things and require different courses of action.

  • Red: This calls for immediate action. If the light is just showing that your screenwash is low or your oil needs topping up, then this is something that can be sorted at the next service station. If it's more serious, such as a brake warning light or temperature warning light, then you may need to call your breakdown cover provider for help.
  • Amber/yellow: Indicates that something's off but it's not urgent. It's still safest to get this checked out by a mechanic as soon as you can.
  • Green (sometimes blue): Indicates that a feature of the car is turned on and running. For example, your full beam indicator usually glows blue to show you've flicked it on.

Key dashboard warning lights to look out for

Make sure you're clued up on which warning lights to look out for and the best action to take. Here are a few example:

Engine Warning Light If the light stays on after starting the engine, get your car checked immediately, even if it feels normal to drive. It indicates that there's something wrong with the engine and you could end up damaging it if you continue to drive.
OIl Pressure Oil is essential to lubricate the engine. It's always a good idea to stop and check your oil gauge. A simple top-up might be all you need if the level's low, but if the warning light remains on after you’ve topped up, it signals that there’s a more serious issue.
Temperature Warning Light Driving with an overheated engine risks a complete engine shutdown. Stop the car, let it cool down and check your coolant (the fluid that helps regulate engine temperature). You might just need more coolant, or there could be a leak that needs repairing.
Brake System If you see this light, don't take any chances, pull over as soon as it's safe to do so. It’s dangerous to drive with a faulty brake, so if the brakes seem ‘spongy’, or unresponsive, stop driving immediately and contact a breakdown professional.
Battery Charge When the battery charge light is on, it means the battery isn't charging as it should, potentially affecting power steering, headlights, and other electrical features. A mechanic should inspect the battery to prevent a breakdown.
