Dashboard Lights: What Do They Mean?

Many drivers have this notion when a warning light illuminates the dashboard. All automobiles include a range of dashboard warning lights related to various systems, such as the engine management light or the oil pressure warning light. When you turn on the ignition in many automobiles, these lights will flash for a few seconds before disappearing. The severity of the problem is indicated by the color of the dashboard warning lights, which range from red to amber to green to blue.

The electronic systems in today’s automobiles rely on a network of sensors linked to dashboard warning lights and symbols. Keep reading to learn more about the most frequent dashboard warning lights and what they indicate.

Red and orange are the two most common dashboard warning lights. A red warning light on your dashboard usually signals a significant problem with your vehicle. If your dashboard warning light is red, you should act promptly since it might indicate an overheated engine, low engine oil pressure, or a brake system issue.

The engine management system — the computer that controls the engine – has discovered a defect, as shown by an orange dashboard warning light. You may drive a car with an orange dashboard warning light, but you should take it to your local service center as soon as possible for diagnosis and repair.

Determine the Car Problem by Looking At the Color of the Dashboard Light

  • Red light: The red light indicates a potentially serious problem, or it can be a safety reminder that requires immediate attention.
  • Yellow/Orange light: It indicates that a specific component needs to be repaired.
  • Green/Blue symbol light: It lets you know that a particular feature of the vehicle is active.
  • Flashing warning light: You must take a look at the component for repairing or servicing.

Checking the engine light

If this warning glows, it’s critical to get your automobile evaluated, even if everything appears to be in perfect working order. This is because it alerts you to a potential engine problem, which you’ll want to prevent at all costs.

This light might appear for various reasons, so while it’s most likely only a malfunctioning sensor or other minor issues, a correct diagnosis is essential to avoid further harm.

Engine Coolant Temperature Light

The red thermometer on the engine temperature light shows that the engine is overheating when it is lighted. If you notice this warning light, you should always pull over and turn off your car since this is a significant condition that can cause catastrophic engine damage. A damaged water pump, a clogged thermostat, a leak in the radiator or one of the coolant hoses, or a cracked head gasket are just a few of the difficulties that might cause the engine to overheat.

Brake Fluid Warning Light

This light illuminates when the vehicle’s braking system has developed a problem. Because the brake is one of the most vital elements of the vehicle, it is critical to get it examined as soon as possible. This light also indicates a low brake fluid level. Fill your brake fluid as soon as possible if this is the case.

Airbag Warning Light

A malfunctioning airbag will not deploy during a collision, which means that the passenger and driver may be gravely wounded, or the bag deployment may be so violent that it causes a shock, resulting in harm.

Battery/ Alternator warning

The presence of this indicator indicates that your battery is not charging. While this has no effects on the ability to drive, the battery keeps on draining rather than charging, which means electrical systems may ultimately fail. You will be unable to restart the vehicle. If no other lights flash when this light comes, continue for a few kilometers until you reach a garage that can assist you.


Tire Pressure Warning Light

A yellow tire with an exclamation point in the center represents the tire pressure warning light. This light indicates that one of the vehicle’s tires is underinflated, and in certain newer automobiles, it can also tell which tire is underinflated.

The tire pressure monitoring system is what causes this light to turn on. If it comes on while you’re driving, pull over and come to a complete stop as quickly as possible. It’s dangerous to drive with a flat or underinflated tire since it might radically change the vehicle’s handling. If any of your tires are flat, call for a tow truck or change the tire if your car has one. If all of the tires are still filled, drive to the nearest service station to check the pressures and, if required, add air.

A puncture, a defective tire pressure sensor, and seasonal temperature variations, which can cause a tire to lose pressure gradually, are all common causes for this light to illuminate.
