I had to take an unplanned hiatus on the Refinery / Building consolidation project to order and wait for some new SMD LED street lights from WeHonest on eBay in China. These LED street lights look great and are fairly inexpensive - especially when compared to traditional options. You will need to do a little bit of soldering before you connect them to a standard 12v DC power supply. WeHonest does supply the correct resistor (680 ohm I believe) for these lights.
So that explains the delay! One of the problems with these lights however, is that a there's about a 10mm of brass tubing that goes through the surface. This is a problem with my little refinery module as I need it to sit flush.
deconstruction, I apparently hid these in a location which can't be found!)
