How to Read the Dashboard Lights

The dashboard, and particularly the instrument panel, represent the easiest way a vehicle talks back to its driver, allowing him to stay up to date with the status of the car and provide him with prior notice on potential mechanical problems. The dashboard items followed the same evolution trend as the whole car, migrating from standard light bulbs to more attractive and efficient LEDs or completely-digitalized dashboard components.

Take for example the head-up display, a technology developed to project important information such as speed, fuel consumption or the tachometer straight on the windshield. Getting back to the instrument clusters, their number increased significantly once car manufacturers developed new technologies regarding safety, engine management or miscellaneous car-related equipment. But more importantly, these tiny lights tracking the operation of the car can provide critical information that could protect you, your passengers and the other drivers on the road.

The number of instrument clusters is huge, mostly due to the fact that most car manufacturers used basic symbols and personalized them for their own models, although we all agree that standard ones would be useful for all drivers, no matter the car they own. That's why we've decided to create a list of the most common instrument panels used by different carmakers around the world, although it could be easily expanded into hundreds.


1. ABS warning light: it is turned on every time there's something wrong with the Anti-lock Brake System. Note that the ABS symbol is activated once the driver starts the engine but it's automatically turned off after a few seconds.

2. Low fuel notification: this panel is switched on if the fuel level gets very low and refuel is required.

3. Seat belt reminder: the symbol appears and remains active as long as the engine is started and the seat belt remains unfastened; depending on the car manufacturer and car model, the seat belt reminder is combined with an audio notification.
