This light base is the COMPONENT that illuminates our cake toppers. LEDs are encased in lightweight, white, plastic and inserted into a small cavity you cut into the top of your cake. Operates on 2 9V batteries (included) for approx. 6-8 hours. And . . . It’s re-useable for other occasions that we can provide other toppers for you! Base can rest on top or if desired may be frosted over. THIS BASE IS NOT SOLD WITHOUT A TOPPER! IT IS MADE JUST FOR OUR TOPPERS. CHOICE OF LIGHT COLORS: Red/Blue/Green/Yellow/Purple/White, please put color choice in the customization box.
