Centerline lights are specialized lighting systems used primarily on runways and taxiways at airports. They help pilots maintain proper alignment during takeoff and landing, especially in low visibility conditions. These lights are typically embedded in the pavement and emit a steady or flashing light to guide aircraft along the center of the runway. In addition to airports, centerline lights can also be found on roads and highways to enhance safety. They provide visual cues for drivers, helping them stay centered in their lanes. This is particularly useful in adverse weather conditions, such as rain or fog, where visibility may be compromised.
