How many strobe lights are present on the aircraft?

The A320 aircraft is equipped with a total of three strobe lights. These lights are part of the aircraft's exterior lighting system, which is designed to enhance visibility and safety during flight operations, especially during low-light conditions.

Typically, two of the strobe lights are mounted on the wingtips, while the third is located at the tail of the aircraft. This arrangement helps ensure that the visibility of the aircraft is maximized from multiple angles, which is crucial for safety when flying in congested airspace or when close to other aircraft. The positioning of three strobe lights contributes to a distinctive look and enhances other pilots' ability to detect the aircraft both on the ground and in the air.

The other options do not accurately reflect the configuration of the A320’s strobe lights, which confirms that the total is indeed three.
