Each light has a specific purpose and can alert you to various issues, from routine maintenance needs to urgent safety concerns. Understanding these lights not only helps you maintain your vehicle but also ensures your safety on the road. At Car Dashboard Light, we’ve compiled a comprehensive guide to the most common dashboard lights you need to be aware of. Let’s dive in!



Overview:

The Check Engine Light (CEL) is one of the most recognized dashboard lights. It appears as a picture of an engine or the words “Check Engine” and can indicate a range of issues.
