when did they add lights to wrigley field
History of Wrigley Field In the fall of 1987, Chicago mayor Harold Washington proposed a compromise ordinance to the Chicago City Council which allowed the Cubs to install lights, but limited the number of night games. Washington died a week after the compromise was proposed, but the city eventually approved a compromise in February 1988 under interim mayor Eugene Sawyer. Major League Baseball responded by awarding the Cubs the 1990 All-Star Game.
