The first ever example of *lights being used to signal road traffic was at the Houses of Parliament in London in 1868. When *carriages carrying *MPs *entered or *left the house during the night or on *foggy days, a *watchman would hold up a *lantern. A red lantern to stop traffic and let the carriages out and a green lantern to signal the other traffic it was clear to carry on.
Modern traffic lights were developed from 19th-century railway signals.
