Various warning lights in cars signal specific issues or conditions within the vehicle. Common warning lights include the engine warning light, oil pressure warning light, battery warning light, ABS warning light, and airbag warning light. The illumination of these lights indicates that the car requires some attention.

When a warning light comes on, it’s vital to understand its meaning accurately. However, not all warning lights imply an immediate emergency. For instance, a warning light indicating low fuel suggests the need to locate a gas station soon but doesn’t necessarily mean you should stop the car immediately.

Warning lights come in different colours, each signifying the level of urgency. Typically, red indicates a serious problem requiring immediate attention, yellow (or orange) suggests a need for caution, and green or blue provides informational alerts. If a red warning light comes on, it’s advisable to park the car safely as soon as possible and seek a professional diagnosis.

The symbols and indications of warning lights can vary depending on the car’s manufacturer and model. It’s important to consult the specific manual of the used car you’re purchasing to understand what each warning light means.

The Security Light indicates that the vehicle’s theft prevention system is active. It usually illuminates when the key is not recognized or there’s an issue with the security system.

Warning lights alert the driver to issues within the vehicle’s systems, while indicator lights inform the driver that a specific function is activated or a particular condition exists.
