asked the Home Secretary whether he is aware of the lack of standardisation of air-raid precautions signs of every description and their lighting; whether any instructions on the subject have been issued by his Department; and what steps he proposes to take to ensure such standardisation throughout the country?

The view hitherto taken is that, provided the signs are legible and visible, their standardisation is not of great importance; but the matter is being looked into.

Is the right hon. Gentleman aware that many of these signs are not lighted at night, and is it not essential that directions to air-raid shelters should be lighted?

The hon. Gentleman will observe that I did make the qualification, "provided the signs are legible and visible."
