Just got in my truck and when I opened the door the chime was ringing. I saw that I left my headlight switch in the on position . Last time I drove it was over 24 hours before I noticed the chime and switch in on position. Last night and upon approaching the truck today the headlights were not on . Question 1...... Do they shut off after awhile when left in the on position ? And if no why were they not on last night or when I got in truck a little while ago ? And ..... Did I just get lucky the battery didn't drain ? Drove it around awhile and everything is fine and multifunction switch is operating as it should? My manual is home and I'm not other wise I would have looked it up, but I thought if you left the lights on ,.....they just stayed on until they drained the battery. Huh, huh , ....Huh, ....I'm like confused and stuf now beavis .lol .
