Spanish Traffic Lights

I've borrowed this off a site (have email back with his permission), they are the perfect item for speeding motorists in villages. I mentioned these a while ago.
Still feeling depressed at meeting. I'm sure it will wear off

Spanish traffic lights.
I would be pleased to know if there are any examples in the UK of 'Spanish style' traffic lights that are used with speed sensors to slow traffic on the approach to villages that straddle main roads. They work by staying at amber if you do not approach too fast, so you benefit from a smooth trip. If you approach too fast they turn red to stop (and thereby inconvenience) speeding vehicles. Few people risk running a red light and friends and neighbours who visit and live in Spain say they work splendidly - and I have recently been told they are used in Portugal too. Enforcement is also easier - a police officer does not need a radar gun. Merely seeing a vehicle going through a red light is quite sufficient evidence (as would be video taken by any local residents).
