Taxiway lights are often mounted somewhat off the paved surface and with frangible couplings which allow them to easily fold over when struck.
Taxiway
edge lights may well be off the paved surface, (remembering that they are only required at larger airfields if a taxiway doesn't correspond with the paved surface), but even so, I don't think these edge lights are that helicopter friendly in the 'frangible' department. If edge lighting is used, taxiway centre line lights are still required.
