I don't really understand why we can't fit IR sensors to them. Surely they only need to be on when someone is walking along?
Cant be done with the lamps traditionally used for street lighting as these take some minutes to warm up.

LEDs start instantly and could be readily controlled by infra red or microwave sensors, and the practice may become widespread. The main drawback is the perception, especially by ladies, that unlit areas are dangerous or at least "scary"

:lol:

It's a Victorian pedestrian suspension bridge that leads to a track along the shore. The bridge rocks like my bed though!

You dirty old man :D

Meanwhile, I really don't like the idea of streetlights that light my way and leave the rest of the place in darkness. I'd prefer all darkness: that way myself and my mugger have an equal sporting chance!

Why would having a rickety bed make me a dirty old man? Oh wait...you thought... :oops:

Hang on..those thoughts are in YOUR head, not mine! :)

Re. the streetlights, I agree. Your mugger has the advantage of shadows and you have the disadvantage of no night-acclimatised vision with which to spot him/her.

At last people are possibly going to understand the security of darkness, and stop being conned by lighting salesmen.

Quite possibly, though there have been improvements - LEDs can be switched on and off repeatedly without problems.

Now you're talking. There's been a concerted effort over here to get walkers, joggers (though not cyclists, strangely) to wear reflective gear and it's having a very positive effect. Next step, street lights off!

As a cyclist I sometimes have problems with reflective kit. It reflects the low winter sun into my eyes and makes it difficult to see stuff. People need to remember that, though crucial at night-time, it's a bloody menace 2 hours before.

For anyone living roughly north of Manchester, tonight and tomorrow should be great times to see the Aurora. Forecast is high due to a large solar flare.
