landing light out at KOKM

Landing light is required for me and my buddy to fly at night, but when we arrived at KOKM, the landing light went out... we couldn't even see the taxiway light, Suddat had to jump out of the plane and I would follow him to the fuel pump. it's kind of dangerous. We called school and the duty officer, they said it was ok for us to fly back, but is it ? it's safe for us to fly back, but it's not "legal"..

... so we decided to take the courtesy car and talk about it at McDonalds.
I'm approaching the final stage of my training, I need to enjoy every minute from now. starting multi-engine soon.
