I did the same thing, but for my wife. She gets pretty bad seasonal affective disorder, and on top of that had a shitty couple of months at work and health-wise. I surprised her by putting up so the lights while she was at work 2 weeks ago. It was the best decision; looking at the lights really helped her SAD, and multiple dog walking neighbors commented to me while I was doing some yard work how much they enjoyed seeing them (our house is very visible entering the neighborhood).

Earthquakes move at the speed of sound, which is incredibly slow compared to light/electricity.
