This colo(u)r changing script is broken and returns no errors, what went wrong?

To give some context, this script changes the color of an alarm light on the click of a button on a Surface GUI. I recognize that it is inefficient but how can I fix it?

parent = script.Parent
alarms = game.Workspace.Alarms
light1 = light1.SpotLight
light2 = light2.SpotLight
glass1 = glass1
glass2 = glass2
SecurityStationFrontAlarm = alarms.SecurityRoomFrontAlarm
SecurityStationLeftALarm = alarms.SecurityRoomLeftAlarm
SecurityStationRightALarm = alarms.SecurityRoomLeftAlarm

script.parent.GreenButton.MouseButton1Down:connect(function() --GREEN PRESSED
	SecurityStationFrontAlarm.glass1.BrickColor = BrickColor.new("White")
	SecurityStationFrontAlarm.glass2.BrickColor = BrickColor.new("White")
	SecurityStationFrontAlarm.light1.Range = 0
	SecurityStationFrontAlarm.light2.Range = 0
	SecurityStationFrontAlarm.light1.Color = Color3.new(0, 0, 0)
	SecurityStationFrontAlarm.light2.Color = Color3.new(0, 0, 0)
end)

script.parent.YellowButton.MouseButton1Down:connect(function() --YELLOW PRESSED
	SecurityStationFrontAlarm.glass1.BrickColor = BrickColor.new("Bright Yellow")
	SecurityStationFrontAlarm.glass2.BrickColor = BrickColor.new("Bright Yellow")
	SecurityStationFrontAlarm.light1.Range = 40
	SecurityStationFrontAlarm.light2.Range = 40
	SecurityStationFrontAlarm.light1.Color = Color3.new(255, 255, 0)
	SecurityStationFrontAlarm.light2.Color = Color3.new(255, 255, 0)
end)

script.parent.RedButton.MouseButton1Down:connect(function() --RED PRESSED
	SecurityStationFrontAlarm.glass1.BrickColor = BrickColor.new("Bright Red")
	SecurityStationFrontAlarm.glass2.BrickColor = BrickColor.new("Bright Red")
	SecurityStationFrontAlarm.light1.Range = 40
	SecurityStationFrontAlarm.light2.Range = 40	
	SecurityStationFrontAlarm.light1.Color = Color3.new(255, 0, 0)
	SecurityStationFrontAlarm.light2.Color = Color3.new(255, 0, 0)
end)

Remember to identify the locations of the items, such as in lines 5-6 they need to have the location of where the brick is

parent = script.Parent
alarms = game.workspace.Alarms
light1 = light1.SpotLight
light2 = light2.SpotLight
glass1 = "LOCATION OF THE GLASS1"
glass2 = "LOCATION OF THE GLASS2"
SecurityStationFrontAlarm = alarms.SecurityRoomFrontAlarm
SecurityStationLeftALarm = alarms.SecurityRoomLeftAlarm
SecurityStationRightALarm = alarms.SecurityRoomLeftAlarm

script.parent.GreenButton.MouseButton1Down:connect(function() --GREEN PRESSED
    SecurityStationFrontAlarm.glass1.BrickColor = BrickColor.new("White")
    SecurityStationFrontAlarm.glass2.BrickColor = BrickColor.new("White")
    SecurityStationFrontAlarm.light1.Range = 0
    SecurityStationFrontAlarm.light2.Range = 0
    SecurityStationFrontAlarm.light1.Color = Color3.new(0, 0, 0)
    SecurityStationFrontAlarm.light2.Color = Color3.new(0, 0, 0)
end)

script.parent.YellowButton.MouseButton1Down:connect(function() --YELLOW PRESSED
    SecurityStationFrontAlarm.glass1.BrickColor = BrickColor.new("Bright Yellow")
    SecurityStationFrontAlarm.glass2.BrickColor = BrickColor.new("Bright Yellow")
    SecurityStationFrontAlarm.light1.Range = 40
    SecurityStationFrontAlarm.light2.Range = 40
    SecurityStationFrontAlarm.light1.Color = Color3.new(255, 255, 0)
    SecurityStationFrontAlarm.light2.Color = Color3.new(255, 255, 0)
end)

script.parent.RedButton.MouseButton1Down:connect(function() --RED PRESSED
    SecurityStationFrontAlarm.glass1.BrickColor = BrickColor.new("Bright Red")
    SecurityStationFrontAlarm.glass2.BrickColor = BrickColor.new("Bright Red")
    SecurityStationFrontAlarm.light1.Range = 40
    SecurityStationFrontAlarm.light2.Range = 40 
    SecurityStationFrontAlarm.light1.Color = Color3.new(255, 0, 0)
    SecurityStationFrontAlarm.light2.Color = Color3.new(255, 0, 0)
