The lights are often used creatively in the FMB for stationary shipping, buildings, vehicles, control towers and other airfield paraphernalia including landing lights.
When objects "dressed" with these lights are destroyed it leaves the lights hanging in mid air, hence the ability for them to be destroyable along with the object would be a great feature.
Search lights are nothing to do with this as they are already destroyable.

Makes sense to me.
