got some machines in, never saw this before! but looking at the LED bulb, the only difference is the plastic outer shield. The tech's measured out 1 foot of LED strip,soldered two wires to the end of it and tied it into the +13vdc. these strips were designed to be cut every two inches and the wire attached to whatever length you want. doing so research I found two types of SMD LEDS, used in the strips,appear to be SMD3528 and SMD5050.Cost could be 8/10 dollar range per bulb. I guess you have to really research the types available, lots of variables,the 5050 are run on 25vdc. Jim
