HC Deb 09 May 1927 vol 206 c39
60. Colonel DAY

asked the Secretary of State for the Home Department whether, in view of the difficulty in correctly observing the signals of police officers on point duty at night, he will arrange for these officers all to wear armlets or white gloves that are luminous?

The SECRETARY of STATE for the HOME DEPARTMENT (Sir William Joynson-Hicks)

A trial is being made of the use of white sleeves, but the Commissioner tells me that none of the luminous devices he has examined is satisfactory.
