Narrative:
Lack of communication between radio electric technician and a&P for proper deferral. A&P assumed that the radio electric technician had pulled indicator bulbs when in fact the radio electric technician felt that the panel was 1 piece and the bulbs did not or could not be pulled telling the a&P everything was set.
