What should you confirm about the turn signals during the light check?

Confirming that the turn signals signal correctly and are functional on both sides of the vehicle is essential for safe driving and compliance with traffic laws. This ensures that other drivers are aware of your intentions when turning or changing lanes, thereby reducing the risk of accidents. Properly functioning turn signals should illuminate and blink in a distinct pattern, indicating the direction you intend to maneuver.

The other options do not address the primary function and safety requirement of turn signals. While having bright colors can aid visibility, it does not ensure their proper operation. Moreover, the functioning of turn signals is independent of the headlights; they should operate regardless of whether the headlights are on. Finally, turn signals are visual indicators and typically do not emit sound, which is more applicable to vehicle horns or alerts rather than indicator lights.
