Narrative:

On feb/mon/03, ZZZ had aircraft X with the captain's attitude direction indicator decision ht light popping the section 6 circuit breaker. The amt removed the bulb from the captain's attitude direction indicator decision ht light due to shorted lamp. The section 6 circuit breaker was reset, and all associated lights were operable. He forwarded the item to maintenance carryover per 34-00-43 upon my interpretation of the MEL. The MEL is for the electronic attitude direction indicator. Aircraft X does not have an electronic attitude direction indicator installed. On feb/tue/03, the attitude direction indicator was replaced and the MEL was removed. There was no exception to the flts the aircraft operated on with the MEL installed. After doing more research, I determined that my interpretation of what an electronic attitude direction indicator is was incorrect, and the information I passed on to the amt was faulty.
