The brake light is usually indicated by an illuminated image of a car with a circle around it.

If either of these warning lights appear on the dashboard, it’s important to get your vehicle checked out as soon as possible. If the check engine light is flashing, this indicates that there is an immediate issue that needs to be addressed. If the brake light is illuminated, this indicates that there may be a problem with the brakes that needs to be inspected and repaired.
