Ladies and gentlemen boys and girls children of all ages I am proud to present my first ever auto light system! I don't know if anyone has done this before but I thought of the idea so hear it is. That's the main component. You dont need the three repeaters I just forgot to remove them. What happens is when the solar panel sends power to the electrical engine it sucks items out of the chest. Next the gates on the build craft pipes read if there are items in the pipe. If there are items it sends a redstone signal that turns off the torches. If the torches are on then your lights turn on*. *Note: The two lights pictured above are not hooked up to this system due to height that I build the machine. In the daytime the torches are off and no signal goes through the wireless transmitter. Here shows the lights that I hooked up. Again the lights hooked up but in nighttime. I don't know if anyone has come up with the idea.
