“Some of us experience the need to use the bathroom in the middle of the night. If you turn on a light, you may lose your night vision. White or blue light makes you lose the sleep hormone, Melatonin, making it more difficult to go back to sleep. So this little light uses one red LED, fastens to the wall, and gives just enough light to see without waking you up as much. The LED is on a swivel, and can be pointed in the desired direction. The housing is 3D printed.
Supplies:
Push button (on-off switch)
Bright red LED
47 ohm ½ watt resistor”
