Vonado Led Lighting Kit for Winter Holiday Train Creator City Building Blocks, Creative Building Brick Kit Model Light Set for Gifts, Compatible for Lego 10254 Building Block Toy(Only Lights)

I bought this by mistake

The instructions seem good, and the parts seem to be on par with other lighting kits, but what they fail to mention is they don't include the Vonado lego power function cable to connect to parts 8878 or 88000 if you've chosen to power the winter train. So you're left with 3 options with this set:1) Remove the lego battery box (88000) or rechargable pack (8878) and fit the lighting battery pack into that spot.2) Try to attach the lighting battery pack on top of the lego battery box or rechargable pack3) Order the Vonado lego power function cable from their site.Overall, not the best options after paying $50 for this lighting set. It's a shame because it has a lot of potential.
