Which feature provides visual signals about the operational status of vehicle systems?

• A. HVAC System Odors
• B. Indicator Lights
• C. Safety Equipment
• D. Coolant Pressure Cap

Answer: (B)

Visual indicators on a vehicle's dashboard are there to show, at a glance, whether different systems are operating correctly or need attention. These lights illuminate to communicate status or faults, letting you quickly assess issues such as engine problems, low oil pressure, charging system faults, or overheating. That makes indicator lights the best fit because their sole purpose is to convey the operational status of various vehicle systems through visual signals.

HVAC odors signal smells rather than system status.

Safety equipment refers to protective devices for occupants and doesn’t provide ongoing status indicators.

Coolant pressure cap is a component related to maintaining pressure; it doesn’t offer visual status signals.
