In order to save electricity and spare bulbs, someone decided that ALSF-2 could be simplified and shortened by turning off the red side rows, the 500 foot roll barettes, as well as the first 1000 feet of centerline bars; this reduces the white lights to a stubby 1400 feet.
At 200 feet prior, change the white centerline to red and widen it by adding a red barette on each side.
