-- I will be forcing each state due to my controls not being sequential
-- I have a toggle switch (On - Off - On) and it will control both low and high beams, so
-- the top On will turn high beams on and the bottom On will turn low beams on. The middle position
-- will just be off.
-- Which makes this variable redundant, but if I do change my controls the logic will be useful
