Dashboard Warning Lights

Dashboard warning lights are your car's way of talking to you. Some are urgent, others can wait — knowing the difference matters.

Dashboard warning lights fall into three categories: red (stop driving soon), yellow/amber (service needed, not immediately critical), and informational (blue high beams, green turn signals). The check engine light, battery light, oil pressure light, and temperature warning are the most common. A check engine light can mean anything from a loose gas cap to a failing catalytic converter — the only way to know is to read the diagnostic trouble codes stored in the computer.

Some lights require immediate action. A red oil pressure light means stop driving now — low oil pressure destroys an engine in minutes. A red temperature light means the engine is overheating. A flashing check engine light means an active misfire that can damage the catalytic converter. Yellow lights like the check engine, ABS, TPMS, or traction control indicate a problem that should be diagnosed soon but usually isn't an emergency.
