I have a 2010 200 series LC.The lights have been, on for a few days then off for a week for the past 12 months.I took it to Muswellbrook Toyota and their very capable workshop manager ,Martin.contacted Toyota ,who claimed it was an electrical fault.After many hours searching [dash out etc]they never found the problem although they thought they had once or twice.To cut a long story short ,they found that the cruise control never worked and the problem was in the computer itself .The computer was replaced and all is fine again. It seems Toyota was right in saying it was an electrical fault.Im very grateful for the effort they made in getting it right again.
