Our Cinnamon/Mustard Timer Tealight turns itself on and off automatically. When it is turned on it will stay lit for 6 hours, then it turns off for 18 hours. The next day it turns back on! It has a textured, brown wax coating and a safe, amber-colored flickering LED light. It is larger than most tealights, at 1-3/4" tall (including the bulb) with a 1-3/4" diameter. Batteries (2) are included, just pull the tab out and switch on. Use replacement battiers AG-13, our item M84020.
