My son ( adult) made his own lego menorah and had no trouble adding the light kit. Looked real good in his window. The grandkids loved it.
The product works, but the instructions just tell you how to connect the wires and then it’s 3 pages ok how to use the ridiculous remote. There’s nothing about a good way to actually place the lights in the lego set and make it look decent. Maybe where I can hide the wires and the logic board.
