§ Mr. Onslowasked the Minister of Transport whether she is satisfied that the light beacons at uncontrolled pedestrian crossings are of sufficient brilliance; and whether she will authorise the development of an alternative installation producing a flashing light of greater intensity, similar to that now incorporated in other hazard warning signs.
§ Mr. Carmichael:To make the flashing of the bulbs as conspicuous by day as by night a tenfold increase of intensity would he needed by day and a return to normal at night. This would also require an automatic switching mechanism. We have looked into this and concluded that it would not be worth the cost. The alternative suggestion would entail redesigning the beacon head and its expense would not be justified by its benefits.
