SOLVED - How to get vehicle data in Scenario lua?

I've just started to learn lua and Beamng modding.
I want to check if the headlights are On or Off in a scenario.

Current scenario's lua snippet :

Code:

local function onRaceTick(raceTickTime)
        local lveh = Lua:getControlVehicle()
        if lveh == nil then print("no vehicle got") end
        lveh:queueLuaCommand("print(electrics.values['lowhighbeam'])")
end

I get the current condition of the lights in the console.

How can I get this in a variable?
