    So I have a peculiar issue which I vent find anything on the forums which are similar.
    It's been happening for a few months now but it's gone from happening sporadically every few months too every day.
    Sometimes, either during the day time or night time, on the day it will stay fishing between Auto headlights on or off. During the day, this didn't matter but at night when it happened I would have to turn headlights to always on.
    Last night, it happened again so I turned my headlights to on instead of auto but the lights didn't turn on, so I put it to auto again and they turned on. The lights turned off again ten seconds later.
    I was then in a constant battle for the rest of the drive turning the headlights to auto every ten seconds to keep my headlights on.

    Had anyone else had experience with this or know what could possibly have gone wrong?

    Have you checked the little dome sensor in the centre of the dash closest to the windscreen? It may be partially covered with a dash mat etc? Or dirty? (although it shouldn't come into play when headlights are switched fully on), or perhaps a faulty headlight switch itself? Do you have a phone mounted nearby that could be playing with the sensor? Perhaps one of the relays under the bonnet (or boot, can't recall exactly but I'm sure there is at least one) is shot?

    sorry just throwing some random ideas up.

    i would suspect a faulty headlight switch/control module, it sends can messages to control the lights so it very well might be the switch playing up.
    you should be able to unplug it when it starts to play up and see if it stops screwing around and if it does stop replace it.

    Did VT come with auto headlights?

    I think the better question is did the vt have a lcd display that would "flash auto headlights on/off"

    If i was the op i would be down at the local wrecker getting a switch out of a wrecked vf.

    No it didn't. Only Berlina (or perhaps Calais?) and above, (ie statesman and caprice) had auto lights.

    VT exec switch on the left. Calais switch on the right.

    I think they turned off when the door opened but if the switch was on, the light would be on while the car was running.

    Yes, thanks Anthony...this is true ie auto off...didn’t have to worry about leaving the headlights on and flattening the battery.

    Perhaps I misunderstood, but I thought (in the context of this thread) that 'auto headlights' referred to the lights either being on or off depending on the ambient light and controlled by a sensor when the switch was set to 'auto'. Of course all VT's turned their headlights off when the drivers door was open, that's not in question.. but I don't think that function is what the OP was referring to, and it's certainly not a function a VT exec has.?

    No, all good tml...it was me who misunderstood. I would be interested tho to know which Commodore series prior to VT was the first to have auto off on all their models. I remember many being critical back in the day (and I agreed) of manufacturers who preferred an audio alarm to remind you that lights were on when you got out. Why not just engineer to turn them off rather than more bells?? I also frequently drive a 2010 Mazda3 that ding, ding, dings at me rather than just look after the lights itself :rolleyes:

    hmmm, well among many commodores, the only ones pre VT I've had, are a VB, a VC and three VS'..I'm fairly certain VS did..and I'm more than certain the other two didn't..:D

    I drive a Magna as a daily..and let me tell you, I would love the 'ding ding' of your Mazda3 rather than the constant 'beeeeeeeeeeeeeeeeeeeeeeeeep' this thing lets out when I forget to turn the lights off..totally agree with you, why the hell wouldn't they just wire in a switch to the door or something so the bloody things turn off.

    OEM’s should just pick either auto lights or beeping. Not Both.
    Any commodore - perfect auto lights set and forget.
    Mitsubishi triton- Beep for 5 seconds then turns self off.
    Nissan Micra - Constant beeping until you lock the car and then the lights turn off
    Missies Mazda 3 - Afformentioned constant beeping - forgets that car wont turn the lights off on its own -come back to dead battery :mad:
