Hi all
Little question
i often forget to turn of my lights
Can i connect the wire that cones from the fusebox to the positive side of the coil
So that when i turn off the key the lights go out as well
Or is there an other solution

Stick a note on the dashboard reminding you to SWITCH OFF THE LIGHTS.

No, you can't do that unless you significantly increase the size of cable from feed though switch to coil.
What you could do is wire the light circuit through a relay energised by the coil feed.

Fit a door switch, connect the sidelights via a buzzer through the switch....if you open the door and the lights are on the buzzer will sound.

Always look at the car as you leave it, and check that the lights are off and the windows closed.

....and that it is locked, and any immobiliser activated. I know, its such a lot to remember!
Coming back to a car with a flat battery in the middle of BFN should be enough not to let it happen again

That would mean you could never have the lights on without the Coil energised.
Not a good move IMHO, to have lights dependant on the IGN being on.
Far preferable to wire a buzzer to a door switch, though personally I find looking back at the car as you leave it is far simpler.
45+ years ago I did wire a buzzer to the door switch on my Mk1 Escort, also using a Diode to stop the connection interring with the interior light circuit.

Well, yes, agreed. Nothing beats just remembering to turn them off.

Your right
I bought a headlight reminder and will install it in the car
I also drive a 2cv and the lights of that car go off when I turn the ignition of
therefor I forget the lights of the Morris
I will make the connection on the door switch as told above
