Final answer:
The correct option is A. Amber. The ABS indicator lamp is typically amber in color and serves as a warning to the driver about potential issues with the anti-lock braking system, which is vital for safe driving.
Step-by-step explanation:
The color of the ABS indicator lamp is typically amber. The ABS (Anti-lock Braking System) indicator is part of a vehicle's dashboard warning lights, which alerts the driver to a potential issue with the anti-lock braking system. It is important for safety reasons that this light is easily distinguishable, hence, an amber light is used because it stands out and is commonly associated with caution or warning in automotive systems.
ABS warning lights are critical for driver awareness, and knowing the appropriate action to take if the light comes on can prevent potential accidents. When the ABS light illuminates, it is a sign that the driver should have the vehicle's braking system inspected by a professional technician to ensure that the ABS is functioning properly. Ignoring an illuminated ABS light could lead to reduced brake performance or a failure in certain conditions.
