B9 base led bulb, E10 LED Lamp Flashlight Replacement Bulb Torches Light. Different color available. LED MINIATURE BULB
75 Mili Amp (mA) 0.47 Design Watts T-3 1/4 LED Miniature Screw (E10) Base LED INDICATOR LIGHT Polarity: Bottom contact must be connected to positive.You might need to reverse the polarity of the batteries (THE BULB NEEDS A SPECIFIC POLARITY TO WORK) Best results when the viewer has a bright white interior (especially the top where the lamp is pointed to) It will not work with vintage transformers (because they are AC) For some people the light will appear too blue. In this case, I recommend the halogen bulb.
