I wish I could do this in a simpler way. Remember the traffic lights I bought a while ago? I sold one on, and kept one. Now I am wanting to make up a simple circuit or management system to drive the Red, Amber, Green lights in a regular sequence. I also want to have the lamps as LED's so that they use minimal electricity as the traffic light could be on for 3,4,5,6 hours at a time. Any clever micro circuit builders on here that have this sort of info stashed in their heads in a fairly simple way?? I have no doubt we have some electrics wizards on here. Could you show us all, or send me a PM please. One of these lights. Currently fitted with regular 220V bayonet fittings. There are a couple of what looks like transformers inside too. That said, nothing is connected, so the actual circuitry can be gutted, as long as I can get something into the reflective parabola's Thanks for any help.

Have a look at Maplin's they may have a ready built circuit, or kit, that you could use/adapt. Sound to light systems would be good.

Do do it with the minimum fuss I would get one of these controllers: Ebay item 230754870381And coil one each of these correspondingly coloured LED strips behind the lenses: e.g. Ebay item 360503112203It all runs off 12V, so car battery would be fine. Or the same folk sell kits with a 12V mains adapter rated for it. The controller has three output terminals meant for red, green and blue lamps. I would just wire the green channel to an orange strip and the blue channel to a green strip to give you the right sequence. There are UK based sellers of the exact same kit on Ebay, just they charge a bit more. Make sure you get the 44 button remote control as it has all the different sequences programmed in and you can vary the speed, etc. I've got some of this kit and it works great. 5 metres of the LED strip is about bright enough to light up a room enough to read by.

^^ Great suggestions ^^ But for that feeling of personal satisfaction, I'm going to recommend the 'old school' method (well, old school to me anyway) of creating your own circuit from scratch with some 555 IC's. I seem to recall making some timer circuits with them when I was at school. A quick search on Google and I've found this: I'm really not too hot with electronics, but reckon this shouldn't be too difficult to do...especially for someone with your skills Rian? Buying something 'off the shelf' is all well and good, but you really can't beat making it from scratch yourself. [edit] I've just realised Ravs link is to a 'self build' circuit....I read it wrong and thought it was a link to a Maplins kit. I'm not going to pretend I fully underdtand it, but it looks pretty easy to make.[/edit]

To get a standard A40 this low, you'd have to dig a hole to put it in

I saw one recently where the guy made his on using a wooden disk with patches of copper on as contacts, one for each colour and the disk was rotated by a barbecue rottiserie motor, disk turns, each copper strip in turn makes contact and completes a circuit to that colour of light, vary the length of the copper and you vary the time the light stays on for, you can overlap them to make two stay on that the same time. Who needs electronics!
