Hello Mr. Page,
The round protective bulls eye lights were on a few large White Star Liners in the past, most notably the Adriatic which was captain Smith’s previous ship before he took command of the Olympic in June 1911. Since captain Smith saw they were not implemented he requested to Thomas Andrews Jr to install them. Thomas Andrews Jr noted is request as following:
“14) Captain Smith strongly recommends protective windows with round bulls eye lights to be fitted in way of square windows on centre shelter navigating bridge as in Adriatic .”
There were no problems during the maiden voyage of the Olympic but captain Smith requested them in case any storm or bad weather could come. Harland and Wolff learned from omitting them from the Olympic during her maiden voyage and installed them on the Titanic before her sea trails began.
I am uncertain about any evolvements on future vessels post-1912, due personal reasons, so I cannot say anything for certain.
I hope this may help.
Yours sincerely,
Thomas
