LED Mason Jar Latterns


By: Ryan Beach

In this easy project you will be taking mason jars and adding a led light and battery circuit to them. It will change your everyday jar into a cool LED lantern.

For this project, you will need:

  • Mason jar(s) in size(s) of your choice (quartpint4oz)
  • 10mm LED(s) in color(s) of your choice
  • CR2032 batteries
  • Wire cutters/snips
  • 3D printed lid with embedded Glow Holder in size(s) to match your jar(s)
  • Paper & scissors, glitter glue, translucent beads, etc. for decorating your jar
  • Calipers or a ruler (optional, for designing your own lid)


I believe that this project relates to engineering because it uses imagination and creativity to take something very boring and simple and make it into a new cooler product. It also uses the basic functions of taking parts and combining them.
