This lesson I put in the lights to the second storey. It was a much quicker process as the walls were thinner on the second storey. I cut little holes so we could attach the LED’s and switches to the wall. Once we had done that I tested the switch to make sure our LED was still working and to make sure no wires were touching. Fortunately they weren’t which speeded up the process further. Once I ahd checked I taped the switch, wires and LED up so they couldn’t fall out or move around. As there was no roof to rest the battery on, I had to tape it to the back of the house along with the wires. I only just managed to install the two sets of lights before the bell went.
