I made for myself a few FSUIPC lua files and a macro file to enable keyboard/button programming lights and battery switch toggling. Figured I'd share in case any one would like to use them or their code:

function dashlightland ()
ipc.lineDisplay("All LANDING Toggle")
ipc.sleep(2000)
    Lights_Approach_Toggle ()
ipc.sleep(500)
    Lights_Flare_Toggle ()
end


function Lights_Approach_On ()
    ipc.writeLvar("L:OHD_EXT_LIGHTS_L_APPR_SW", 1)
  end

function Lights_Approach_Off ()
    ipc.writeLvar("L:OHD_EXT_LIGHTS_L_APPR_SW", 0)
end

function Lights_Approach_Toggle ()
	if ipc.readLvar("L:OHD_EXT_LIGHTS_L_APPR_SW") == 0 then
      Lights_Approach_On ()
	else
      Lights_Approach_Off ()
	end
end
---
function Lights_Flare_On ()
    ipc.writeLvar("L:OHD_EXT_LIGHTS_L_FLARE_SW", 1)
end

function Lights_Flare_Off ()
    ipc.writeLvar("L:OHD_EXT_LIGHTS_L_FLARE_SW", 0)
end

function Lights_Flare_Toggle ()
	if ipc.readLvar("L:OHD_EXT_LIGHTS_L_FLARE_SW") == 0 then
      Lights_Flare_On ()
	else
      Lights_Flare_Off ()
	end
end

function Light_LandingAll_On ()
    Lights_Approach_On ()
ipc.sleep(1000)
    Lights_Flare_On ()
end
function Light_LandingAll_Off ()
    Lights_Approach_Off ()
ipc.sleep(1000)
    Lights_Flare_Off ()
end

Thanks for this! How did you identify the LVARs?
