In 1964, the club invested £50,000 to upgrade the floodlighting system – installing their revolutionary six-pylon system which each stood at 175 feet high.
This took the total number of lamps to 324, meaning Boothferry Park now enjoyed the best floodlights in the Football League at this time.
The lamps were first used for an evening league when Barnsley were the visitors on 7th October 1964, a match the Tigers won 7-0.
The floodlights were finally dismantled in early 2011, nine years after City played their last game at Boothferry Park.
