For the automatically night light I use a solar garden light.

This is the easiest way because you only need to dissemble it and make some wires longer and finally mounting all in the bulb and base tin.



Remove all screws and get the circuit with the LED out of the housing.

Cut the wires to from the solar panel to the circuit.

Cut with a cutting wheel from the Dremel the solar panel out.

Solder out the LED and solder two long wires on.

Later the circuit is placed in the base tin with the switch and battery and the LED wires goes through the brass tube to the bulb.



Drill two holes into the tin then fit the switch in one and take the wires for the solar panel out.

Take care with duct tape that no parts of the circuit has contact to the brass parts!

If you have checked all parts again you can switch the power on.

When you hold your hand above the solar panel it must switch on the light.

When the solar panel is in the light it will charge the battery.



Very important:

To bend the small brass tubes is necessary to filled it with sand!

Only if your pipes filled with fine sand you can bent the brass tubes, otherwise you pipe kink directly and is destroyed.



I filled the tubes with bird sand and sealed at the ends with electrical tape.

Then I use a brake pipe tool from Hazet (Art. Nr. 2193-1) the bent the radius.





The last picture show you an only battery powered version with a CR2032 cell.
