10x E10 Lamp LED Bulb 3V 3.5V Volt White MES 1447 Screw for Torch bike bicycle

These are good bright LEDS. I was able to do what I wanted with them.I wanted to upgrade a very old torch, which I was able to do with some rewiring. (I must emphasise that this would not be an issue with a normal torch, as mine had non standard internal wiring The designers my of the torch totally ignored polarity conventions which would not have been an issue in the days of filament bulbs!)

Utilising in vintage (WW2) blackout lamps
