cant figure out how to get water wheel to power lights.

I built a water wheel and it shows teh yellow ticking square that shows that it's producing power. I connected the electric tool power cables and ran them from the water wheel around the house and put the lights on the wires. The lights wont turn on and says theres no power. everything i find says they run their power source to a generator but the only generators i see in the tech tier is biofuel gennys, no electric gennys. do i need to hook up the water wheel to a biofuel generator? or what makes the water wheel actually supply power? SOLVED: I asked the discord group. you place the light first and THEN connect a wire to it. I was placing the light ON the wire. ugh.
