| S/W. Hs{Lord Ernest Hives - Chair}/WST WST LE8/C/16.10.34. 86153. Re Fitting of Wireless Sets. There is always the possibility that the wireless set may be left on with the consequent result of running down the battery, etc. Do you think it would be advisable to fit a red warning light in circuit with the wireless or get Philco to increase the intensity of the light behind the dial and put a deflector so that this does not interfere with the driver's vision when driving at night? On the latter point I have spoken to Mr. Hornby and he is looking into this and will see what suggestion they can make as well. J.I.E. | ||
