what value resistor are you using? It will take at least six volts to light it if it's the circuit I posted. There are three sets of two LED's each in series, and the three sets are in parallel. If you put at least 5.5-6.0 volts on it, it'll light. That presumes that all the LED cathodes face the proper direction, see arrows in the graphic below.
