Step demarcation lights — a fluorescent or LED light, traditionally colored green, is located inside the escalator mechanism under the steps at the boarding point. The resulting illumination between the steps improves the passengers' awareness of the step divisions.

Huh? I, myself have never checked to see how the light under there is. Next time I go I'll check. Oh, and I have no idea whatsoever to why.
