There is no external power to fail.
The strobe light is only for easy field identification at a distance and would be off for the landing.
The strip would have 14-18 separate edge lights with completely independant solar powered batteries.
The runway would be lit from 3 miles on final by retroflectors similar to those approved by the FAA / CAA, using the aircraft headlamp as source.
These items are all falable, just as anything we do is. As earlier mentioned. If any component that is required fails, then there are options available. Multiply independant systems is probably as good as could be hoped for, and much better than most of the other stuff in the aeroplane!!!
Care will clearly be needed.
