The PSO-1 bulbs are quite rare and expensive. In this video I show you how to fix a broken bulb. The original bulb is replaced by an LED. You can choose any colour LED you like.
Keep in mind the polarity of LEDs. Be carefull when removing the bulb, the original soldering probably contains lead!
I used the original battery cap, not the AA conversion. I applied a spring onto the connector of the original battery cap for making it compatible with any 3 volt disk-like battery cell.
I used the following tools and items to rebuild the bulb:
Hobby knive
Sanding paper (180 grid will do the job)
Dremel tool OR a file (for cutting the edge on the LED)
Electric drill (for mounting the LED when cutting the edge)
Soldering iron
LED (which works on 3 volts, any colour you like)
Soldering tin
Pliers (when soldering)
If you have any questions, feel free to ask!
