Lot of 5 Mini 3 LED strip w/resistor soldered on strip. Half the length at 1" long of our regular strips. 12 volts, but will work at 9-15 volts D.C. Two 6" red & black flexible wires. No heat, so no melted plastic. Fits perfectly in model buildings. It has 3M adhesive backing but we recommend gluing it in for longevity.
