I have got a TON of Christmas lights. They could work- but selling as craft items only. Have not been tested.

Add a pop of blue to your Christmas decor with these C7 incandescent bulbs. Perfect for crafts and decorations, these bulbs are untested and sold as-is. The bulb shape code is C7 and they are intended for replacement use only. The sensor type is light and the lighting technology is incandescent. These bulbs are ideal for collectors and holiday enthusiasts alike. Make your Christmas merry and bright with these festive bulbs.
