tkaz, I also think it's neat that the light comes on after coins, but, it only lasts for a few seconds, until you vend. However, I may experiment, as you suggested. The Blue is connected to "Common" and the Orange is connect of "Normal Open". By twisting them together, would they both go on "Normal Open", and the Common be naked?
Great advice on the LED bulb. Are you using them? Are they as bright as incandescent bulbs?
I found them at my English Gardens nursery store, ( they are C7 direct replacements for a standard Xmas tree lights & they were on clearance sale post Xmas) Yellow seems the brightest but I've seen them in a blueish/white that's fairly bright, but them were sold out of th e"white" by the time I got to the sale...Yellow still looks pretty good though! PS... they ran $5.00 for a pack of 4-lamps, red.green,blue & yellow.
