function GetLightsToChase()
	local Lights = game.Workspace.Tower:GetChildren()
	for i,v in pairs (Lights) do
		if v:IsA("SpotLight") then

First, I think a SpotLight needs to be a direct child to a BasePart or Attachment, it couldn’t be directly a child of the model, so you might need to change the line to:

local Lights = workspace.Tower:GetDescendants()

Then to detect the distance between the NPC and the light, just compare the position of the NPC model’s PrimaryPart to the position of the parent of the SpotLight object with something like this:

local Distance = (NPC.PrimaryPart.Position - v.Parent.Position).Magnitude

Try this function. Put a table of all the lights you want to detect. Also put the char(model) of the NPC or player you would like to test.

function IsCharInLight(char,lights)
	local root = char:FindFirstChild("HumanoidRootPart")
	if root then
		for i,v in pairs(lights) do
			local lightParent = v.Parent
			if lightParent:IsA("BasePart") then
				if (root.Position-v.Parent.Position).Magnitude <= v.Range then
					return true
				end
			end
		end
		return false
	end
	return false
end
