Same as you're already doing obviously

	if mouseWidth>18 and mouseWidth<23 and mouseHeight==2 then
	  rs.setOutput("left", true)
	  m.setBackgroundColor((colors.red))
	  m.setCursorPos(18,2)
	  m.write(" On  ")
	  m.setBackgroundColor((colors.lime))
	  m.setCursorPos(24,2)
	  m.write(" Off ")
	  m.setBackgroundColor((colors.black))
end
	if mouseWidth>24 and mouseWidth<29 and mouseHeight==2 then
	  rs.setOutput("left", false)
	  m.setBackgroundColor((colors.lime))
	  m.setCursorPos(18,2)
	  m.write(" On  ")
	  m.setBackgroundColor((colors.red))
	  m.setCursorPos(24,2)
	  m.write(" Off ")
	  m.setBackgroundColor((colors.black))
end

just edit the if condition to wherever the button is.

i have try that, but it didnt work

Show us the code you tried, then. Also post any errors you got, a description of what you did, how the code responded, and what makes you think it "didn't work". Just saying it didn't work doesn't tell us anything useful.
