HC Deb 24 March 1971 vol 814 c118W
Mr. Mulley

asked the Secretary of State for the Environment if he will publish the findings of his Department's examination of the use of flashing lamps to mark the extremities of road works and similar purposes; and if he will now amend the Traffic Safety Code for Road Works to permit battery-operated flashing danger lamps to be adopted by authorities desiring to use them on grounds of efficiency and economy.

Mr. Peyton

I am still examining various types of lamps. Efficiency and economy are important but the effect on drivers must also be considered.
