Headlights left on warning buzzer

I've had a couple of times when leaving the car parked during the day of forgetting to turn lights off (Is it a sign of advancing years?!), fortunately without suffering a flat battery as not parked for long.

I've bought a buzzer to remind me, and the instructions kindly mention the door operated courtesy light switch (!!), but also state connection is made to headlight wire and ignition switch wire as the connections to be made.

Trouble is, having looked under dashboard at switches, I can't see any easy way of splicing the two wires into the respective cables as there is hardly any space, and little 'free wire' to use. Same applies to fuse box (bring back the old screw terminal boxes I say.... showing my age here!!).

Anyone found an easier way to wire one of these in, or should I just try to remember to switch them off without help?

You could make short Y pieces with appropriate termination that give you a new connection from one limb and recreate the switch connection from the other two: all the difficult stuff done on the bench.

There are piggyback fuses that might help, but I think that what you are trying to do means you need the connections downstream of the switches.

I did this a few years ago (on a 2001 K-Series).

I seem to recall I used piggy back spade connectors (so no need to cut into the existing wiring loom, and can simply be removed later if necessary).

The "Headlight" connection can be taken from the Main/Dip toggle switch (it's the 'pole' of the switch that should have a Blue wire already going to it).

The "ignition switch" connection can be taken from either:

  1. Green wire from the brake light switch in the pedal box (10A fused F1)
  2. Green wire to the heated screen switch is connected to a spare green wire (probably near the Tacho/Speedo) intended for an “optional low oil pressure warning light feed” (10A fused F4)
  3. Orange wire to the Wiper or Washer switch (15A Fused F10)

The unit I used (Velleman K3505 kit) didn't have a door switch, but I guess it you leave those contacts open then it will buzz as soon as you turn off the ignition with the lights left on (which is what mine does) Wink

Thanks to you both, as ever a great help in solving one more of the 7's mysteries, and much appreciated!

I continue to be amazed and delighted with the support available from the forum....... this is without doubt the best club I have ever belonged to!!

The other option is to go for an external kill switch, which is mandatory for some forms of motorsport. Caterham do a kit and it fits into the triangle at the bottom of the windscreen on the driver's side. The big red 'key' is simply removed after switching off the engine. Kills all electrics, which can help avoid a fire and makes the car a bit harder to nick.

After much poking under the dash, It appears that my car (K Series) has a live feed to the Main Beam Flash switch! Seems I've got to find another Ignition controlled  source that's easy to get to.

Having tried some other ways of connecting the buzzer unit, all I've discovered is that I can get it to operate all the time, but can't find a way of silencing it with the Ignition on. Might have to try another make of unit? This one has just a red wire (connect to Headlights) and a black wire (connect to Ignition Switch), but that seems to be the same as most others I've looked at!

Can you tell us any more about the unit: model, photos, instructions?

If you don't have any of those or the instructions aren't clear I suggest playing with it on the bench with a battery and multimeter before going near the car. That would test the wiring logic and that it's working correctly.

hi Jonathan - hope these help. Not sure of make as it was bought on Ebay. maybe I'd be better sticking to a known brand, as ian B mentioned!

They're a bit small. (And I can never adjust the size of images served here.)

Can you enlarge them, or describe the wire colours and what the instructions say about each of them.

Finding a switched live feed behind the dash won't be difficult.

Can't seem to upload larger than this!First Instructions are for when Ignition is off and Lights left on - It has a Red Wire ('Connect to Headlight Fuse' ) and Black wire ('Connect to Ignition Fuse'). Second part of instructions is for after door has been opened with lights left on

I have tried connecting to Blue Wire on Dip Switch and Ignition controlled Feed to Indicator switch - this makes it buzz when indicator is switched to left/right, but makes no difference if headlights are on.

beginning to wonder if this is something to do with Immobiliser, (which is not standard Rover - it has a coded key that goes into a socket on dash), Although this makes no difference when trying to get this to work.

With Ignition off, all Lights can be put on/left on, and dip flasher also works, so maybe it is not wired conventionally?

I fitted a cheap battery master switch through the bulkhead next to the fuse rail .... so it can be accessed from the passenger side of the cockpit (reachable by the driver). Terminal studs are in the engine bay near the battery. I turn it off every time I leave the car. Prefer it out of sight, rather than on the outside of the car.
