Understanding Your Car Dashboard Warning Lights

Dashboard warning lights use colour for a reason — knowing roughly what each colour means helps you judge whether something can wait until your next service or needs attention right now.

Red lights: stop and check

Red generally means a serious issue that could cause damage or affect safety — things like the oil pressure warning, engine temperature warning, or brake system warning. If a red light appears, especially with an unusual noise or smell, it is usually best to stop safely and check rather than continue driving.

Amber/orange lights: get it checked soon

Amber typically indicates a fault that needs attention but is not necessarily an immediate emergency — the engine management light, ABS warning, or tyre pressure warning are common examples. It is still worth booking this in promptly rather than ignoring it long-term.

Green and blue lights: informational

These usually just confirm something is switched on — indicators, main beam, fog lights — and do not indicate a fault.

The engine management light specifically

This one covers a huge range of possible issues, from a loose fuel cap to a genuine engine fault. If it comes on steadily, get it diagnosed when convenient; if it flashes, that usually points to something more serious and is worth checking sooner.

When in doubt

Your owner’s manual has a full symbol guide specific to your car — worth a quick check the first time an unfamiliar light appears rather than guessing.
