I found this in the Compiler.txt

LightsOn.cs(33,17): warning CS0414: The private field `Oxide.Plugins.LightsOn.Nighttimer' is assigned but its value is never used
LightsOn.cs(34,17): warning CS0414: The private field `Oxide.Plugins.LightsOn.Alwaystimer' is assigned but its value is never used
LightsOn.cs(35,17): warning CS0414: The private field `Oxide.Plugins.LightsOn.Devicetimer' is assigned but its value is never used
LightsOn.cs(1228,4): warning CS0162: Unreachable code detected
LightsOn.cs(1206,9): warning CS0219: The variable `hasperm' is assigned but its value is never used

Those are not errors, and can be ignored.
