Sir, – I agree with David Reddy (October 27th) when it comes to traffic lights in Dublin impeding the smooth flow of traffic. I am old enough to remember the "Winking Willies" at many intersections in the late 1950s. These signals flashed red in one direction and amber in the other, signifying the care necessary to negotiate a junction. Surely traffic lights could be programmed to revert to flashing during off-peak periods, allowing road users to use "common sense". – Yours, etc,
ARTHUR TANNER,
