Dashboard warning lights are your car’s way of communicating important — sometimes critical — information. Knowing what these symbols mean can help you act quickly, avoid damage, and stay safe on the road. Here’s a guide to the most common warning lights UK drivers should recognise.
1. Engine Warning Light (Check Engine)
Indicates a problem with the engine or emissions system. A steady light often means a minor issue, while a flashing light could signal a misfire or more serious fault. Have it diagnosed as soon as possible.
2. Battery Warning Light
If this light comes on while driving, it usually means the charging system isn’t working properly. This could be due to a failing alternator or battery connection — don’t ignore it, as your car may soon lose power.
3. Oil Pressure Warning
Low oil pressure can lead to severe engine damage. If this light comes on, stop the vehicle and check the oil level. If it persists, seek professional help immediately.
4. Brake System Warning
Could indicate low brake fluid, worn brake pads, or a more serious fault. It’s essential to get this checked urgently — brake failure can be dangerous.
5. ABS Light
Signals a problem with the Anti-lock Braking System. The car may still brake normally, but ABS won’t function in emergencies, reducing your ability to stop safely.
6. Tyre Pressure Monitoring Light
Tells you one or more tyres are under-inflated. Check and adjust tyre pressures promptly to maintain safety and fuel efficiency.
7. Airbag Warning
If this light stays on, there may be a fault in the airbag system. In a crash, the airbags may not deploy — get it inspected immediately.
