I made a giant jack o lantern face that has lights that not only turn on at night, but also flicker a little to simulate a candle inside the eyes.
It took a while to figure out, but I’m proud of the solution I found out. I wound up using two red stone clocks that are always on to cause the flickering effect, and only having the circuit complete at night by using a daylight sensor and some sticky pistons to complete the circuit.
