Narrative:
I was instructed by my lead mechanic to change the nose landing gear spot light. The aircraft was on a delay already. The nose landing gear doors were opened by my lead mechanic so I could change the spot light. My lead and another mechanic were servicing hydraulic in the right wheel well. I finished changing the light and went over to the lead by wheel well to tell him my job was done. I neglected to close the nose landing gear doors when I finished. 2 operations people were on the tug waiting for us to finish. These doors have no indication in cockpit for crews. They are returned because of nose vibration.
