Warning lights in a car serve as critical indicators of the vehicle's health and performance. These lights communicate various issues, ranging from minor alerts to serious malfunctions that require immediate attention. Understanding these symbols is essential for maintaining vehicle safety and preventing breakdowns.

Types of Warning Lights

There are generally three categories of warning lights based on their color, which indicate the severity of the issue:

  • Red Lights: These signify serious problems that require immediate action, such as engine overheating or low oil pressure. If a red light appears, you should stop driving as soon as it is safe to do so.

  • Yellow/Orange Lights: These indicate caution and suggest that something is not functioning correctly. While you may continue driving, it's advisable to check the issue soon.

  • Green/Blue Lights: These lights provide information about systems that are currently in use, such as turn signals or high beams.
