If there is existing illumination for the area where the equipment is located, there is no requirement to provide an additional lighting outlet.Would a sump pump require a light? Laundry tray pump?
In most instances, why wouldn't the existing illumination suffice or be made to suffice?
Don't service people carry drop lights or other portable lighting?

It's dark under that sink.No idea of how you would use a laundry tray without existing illumination.
