To draw Christmas lights, start with a circle for the bulb. Then, add a smaller circle inside it to represent the light bulb's filament. Add some lines for the wires connecting the bulbs to the power source. You can also add some shading to the bulb to make it look more realistic. Finally, add some decorative details like holly leaves and berries or snowflakes around the bulbs to make it more festive. I hope this helps! Let me know if you have any other questions.
