From the online description:
Cripple Creek's lighting needs the Menards Plug & Play 4.5 volt power supply, sold separately. Check Menards SKUs 279-4061, 279-4062, or 279-4050. You may wish to consider the 8- or 9-piece Plug & Play accessory kits (SKU 279-4035, 4681) and to serve several structures or vehicles.
