Where can I find instructions on how to install the coop light?
You can find instruction on installing the coop light here - https://www.omlet.co.uk/files/public/manual/2021/04/Instruction-Manual-AD-Motor-Assembly-Replacement.pdf.
There is also a really helpful YouTube video here - https://www.youtube.com/watch?v=14s9GzS0b4M&t=2s.
