Car warning lights are dashboard symbols that signal your vehicle’s condition. They indicate issues ranging from routine reminders – like low fuel – to urgent problems such as brake or engine failure. Understanding these symbols ensures your safety and prevents costly breakdowns.
Why You Should Know Your Car’s Dashboard Lights
Your dashboard is like a real-time communication tool between your car and you. When something’s wrong, your car speaks through symbols – not words.
Modern vehicles come with an onboard diagnostics system (OBD-II) that monitors the engine, transmission, brakes, and other components. If something isn’t working as it should, a warning light appears.
Ignoring a warning light can lead to:
- Costly repairs later
- Unsafe driving conditions
- Sudden vehicle breakdown
Knowing what these symbols mean is the first step in responsible car ownership.
Types of Car Warning Lights
Car warning lights generally fall into three categories:
- Red Lights – Urgent alerts that need immediate attention
- Yellow/Amber Lights – Advisory alerts; check the issue soon
- Green/Blue Lights – Informational alerts or system status (e.g., headlights on)
