Can anyone explain what happens to the snow when it has been pushed to the edge of the runway? The runway edge lights are on small stalks, but it seems to me that as soon as there is any significant amount of snow, they must end up buried in a snow bank. Do they have to dig them out individually? Presumably at airports where they expect a lot of snow, they use blowers to blow the snow well clear of the runway edge.
Gatwick's edge lights are inset/flush mounted therefore snow ploughs are not a problem the excess snow is pushed well clear of these fittings.
The lights shown in the previous photo of snow clearing at Gatwick are not runway edge lights.
