It’s the same thing every time, no lamp in place when you need one - so why not build a lot of these - always in place !
* 1 fresh 9 Volt battery
Start with localising the anode (+) and cathode (-) of the LED. Mark them up as I did (with a felt-pen), red for anode (the longer leg) and black for cathode (shorter leg and phased edge on the bottom of the plastic of the LED). I will in the following text write red and black.
Now to the LED’s. Carefully bend the legs towards each other, hold between the plastic and bending point with a prier as you see in the picture.
Solder the legs together, with red to black in all three LEDÃ¢â‚¬â„¢s, put them as tight as you can and solder quickly,
