I have a LS200 that has problem with headlights coming on during night and running battery down. Also left shift turnsignal turns lights on to bright so suspect problem going to be in signal switch. Anyone else had this problem? Fixing to have to troubleshoot. Any suggestions?

Sounds like the switch hasbroken internally, and you got a piece of metal floating around in there - replace it.

thanks for your advice. sounds right to me. Wasn''t able to check out vehicle today since son driving it to work but will shortly. Let you know if takes care of problem.
