Toyota Camry 2010: Constantly replacing hybrid light globes

My friend and I are having trouble with light globes on our Camry Hybrid taxis. They have both been on the road since March and have done 80,000 km. In that time we have replaced the low beam globes six times. Every exterior light globe has been replaced between four and six times. The Prius's that are also used as taxis do not have this problem, one has been on the road for three years and done in excess of 300,000 km and has only required three low beam globes in that time. Anyone using a Camry Hybrid as a personal car might not experience these problems, as they would not be doing the night hours we do and probably would not have to replace any globes in the lifetime of the car.
