Blue Cross Blue Shield of Michigan illuminated its 21-story office tower on East Lafayette in downtown Detroit with a ten-story-high white light display with the initials “J D”, in a tribute to the late Congressman John Dingell. The lights were visible at dusk on the building’s north side. The building was lit to pay homage to the life and legacy of John Dingell, a Michigan icon and champion for the state and nation. Also, the structure is lit occasionally to commemorate special events and occasions. A red heart is lit in LED lights each February to recognize American Heart Month and encourage prevention of heart disease which remains on display on the building’s south side.
