OK, another challenge. I bought this for pennies at Stafford show, from the dangerous second-hand stall. It was cheap, orange, and I wanted to know more about it. Rather then dig out the box contents like most people would, I handed over some cash (OK, added it to the pile of stuff I was buying) for future investigation.
Inside, we have an orange box, some lamps, a bit of wire, and a diagram. It appears that there are many options for flashing light combinations. I still can't work out why you'd use them though.
Inside the box, there's some serious circuitry, but no relay as I was expecting.
So, I'm not really much the wiser. Anyone got an idea what this is, and where I could use it?
