I replace the normal LED bulbs in tea lights with green candle flicker LED bulbs to make an easy to operate decorative holiday light. Each set includes 3 converted tea lights and 10 extra CR2032 lithium metal button batteries. I use a good quality tea light and solder in a 5mm bulb to create a highly visible, easy to operate accent light that fits nicely in your holiday displays. The lights have an on/off switch, making it easy to extend the battery life. If you are looking for a different color or mixed colors, contact me before ordering to discuss options. Lights are made to order, but I will try to ship within 3 business days. Battery brands may change, due to availability but will ba comparable to what's shown.
