#1130: Cartalert

Shopping trolleys in a wintry supermarket carpark are hard to see amongst the various milling pedestrians and manoeuvring vehicles.

Today’s invention is to equip each trolley with a head-height lamp on a stalk, ideally rotating like those on ambulances. These carts cost about £400 each, so the addition of a lamp would be still a small extra.

Such trolleys might also be given indicators so that cars could be made aware of which way they were going to turn (Once in motion, these can be hard to change direction and motorists need to give them a very wide berth indeed….especially if the ground is icy).
