Now I know why Vader was so angry. He saw his electric bill.
I made this as a reminder that following in Vader's footsteps is not only fun, but can save you some cash as well.
This is a slightly over sized wall switch plate cover. Switch to Vader to go to the Dark Side (off), or to Luke to stay on the light side (on).
After printing, I used a black Sharpie to color in the lettering for Luke, and the plate for Vader.
