Narrative:

At departure time; crew chief asked over headset if cargo doors were closed. I told him they were closed and asked him why he asked. He responded that he had trouble with his door closed light. I responded that they were closed and asked first officer who was on gate control to request pushback. After pushback and before disconnecting crew chief asked me to make a note of the problem. I responded that I would. I didn't think anymore about it as on all previous aircraft I have flown; cycling cargo doors to get the lights out is a very common occurrence. I later discovered that in the MEL his door light is a required item. I checked the maintenance history the next day and found no reports for the ground cargo door light; so am confident that it was not inoperative. I submit this report because after thinking more about the situation and discovering how important the ground light is; I should have asked more questions.
