HC Deb 01 June 1960 vol 624 c140W
Mr. Mason

asked the Postmaster-General if he will consider the possibilities of having small light bulbs fixed to each of a group of office telephones so that users may quickly ascertain which telephone is ringing.

Mr. Bevins

I can arrange for separate lamp signals to be specially provided in association with any office telephone, and this meets most needs. The development of a lamp on the telephone instrument itself is under way.
