Tea light timer is controlled by an ON/OFF switch located at the bottom of the candle. When the switch is turned ON, the tealight will remain lit for 6 hours and then automatically switch off for 18 hours. After 18 hours the tealight will automatically turn on again.
The tealights come with complimentary AG 13 button batteries for display purposes. Additional batteries can be purchased at the Hearthside Collection, item #84020.
