So I managed to get my hands on this traffic light and I posted orignianlly about how I might go about getting them to flash in some specific order. Now I just want them to flash randomly. Each of the 3 lights has its own hot wire and then there is a neutraul wire connected to all three. I just wanted to know what I would have to do to get them to blink on and off. Any help would be great. Thanks in advance.:)

How cool!

I figured this would be an easy one: Lowe's and HomeDepot carry a random controller for single lights, but I've not been able to find something that I'm sure will work for you.

The closest I got was the Plug in Controller/Timer halfway down the page here.

Something like this might work, too.

If someone does not come along to point you to one that will work for sure, give a local RadioShack a call and ask them if they've got something in their commercial catalog that will work.

Find a local shop (or internet) that sells electronics for discos (revolving lights etc). How about this on eBay uk: Disco Light Controller
