What is a Dashboard Warning Light?

A dashboard warning light is an illuminated symbol or icon on your car's instrument panel that signals a problem with one or more of your vehicle's systems. These lights are designed to catch your attention, as they can indicate anything from a minor issue that requires immediate attention to serious problems that may lead to costly repairs.

Common Warning Light Symbols

• Engine Management Light (MIL): This light resembles an engine and is one of the most common warning symbols. It indicates a problem with your car’s engine control system.
• Oil Pressure Light: A dipstick-like image shows low oil pressure, which can lead to engine damage if not addressed quickly.
• Battery/Charging System Light: This symbol looks like a battery or plug and indicates an issue with the charging system, alternator, or battery.
• Tire Pressure Monitoring System (TPMS): A tire with an exclamation mark shows that one or more tires are below their recommended pressure levels.
• Brake Warning Light: A brake pedal or red circle with an exclamation mark indicates a problem with your braking system.
