Well, taxying last night between the parallel runways an entire section of about 400 metres of green centreline lighting failed in front of me.
This evening, told to hold short of a taxyway, I noted that of 7 amber lights marking the hold-short point before said taxyway, only one was operational.
Certainly doesn't make life any easier I would say, but at least the purpose-built airport layout makes it simpler to navigate around than some others which spring to mind!
