Which shows how to make some cheap street lights. I've had a go, but with a few modifications due to cost etc.
Using some 3V parasol lights from a pound shop, I stripped out the bulbs and used them instead. I also used the brass tube as one feed, as I mentioned in my post on the forum.
Total cost for the materials
£3.80 for tube
£2.50 for rivets
£1.00 for lights
Using 100mm lengths for each light gives a cost per light of less than 70p
