Willis Lamm's Traffic Signal Collection Clicking on a picture will bring up a larger view in a new window.   UK Signal Sequences Signals in the UK have a somewhat different sequence than those in the USA. In addition to the customary amber display between green and red, UK signals display a brief amber along with red just before dropping to green. This "wake up" display allows motorists to engage their manual transmissions and be ready for the green light. The customary sequence is: Green Amber (3 seconds) Red Red and amber (2 seconds) Back to green

Green Red

Amber (3 seconds) Red with amber (2 seconds)
