What is one method to check if brake lights are functioning?

• A. Test the lights with a multimeter
• B. Have someone depress the brake pedal while you observe from behind
• C. Check the fuse related to the brake lights
• D. Use a scanner to diagnose the brake system

Answer: (B)

Having someone depress the brake pedal while you observe from behind is a practical and straightforward method to check if the brake lights are functioning. This approach allows you to visually confirm whether the lights engage when the brake pedal is applied, ensuring they illuminate as expected. Observing the lights in this way helps identify if there are any issues with the bulbs themselves or if the wiring is faulty. This method is effective because it requires minimal tools and can be done quickly without additional equipment. It provides immediate feedback on the operational status of the brake lights from the driver’s perspective.
