Know of a script for controlling lights?

I wrote something like that once…

try (destroyDialog LightSwitch) catch ()

rollout lightSwitch "LightSwitch"
(
	button lightsOn "Lights On" pos:[5,10]
	button lightsOff "Lights Off" pos:[90,10]

	on lightsOn pressed do
	(
		if $ != undefined then
		(
			for l in $ where superClassOf l == light do
			(
				if isProperty l #on then l.on = true
				if isProperty l #enabled then l.enabled = true
			)
		)
	)

	on lightsOff pressed do
	(
		if $ != undefined then
		(
			for l in $ where superClassOf l == light do
			(
				if isProperty l #on then l.on = false
				if isProperty l #enabled then l.enabled = false
			)
		)
	)
)
createDialog lightSwitch
