I am in NJ, USA and I am trying to convert the wiring of an outside
light from 2-way to one-way.
The light was previously controlled from inside the kitchen and also
from the garage but the garage switch is now completely isolated and
disabled.
What I have is black, white and red wires (plus unsheathed earth)
coming out of the box for the wall-light and the same coloured wires
coming out of the switch-plate. Near-miss accidents have confirmed
that the black and red wites going to the switch box are live, I have
no idea about the white wire.
I believe that the red wire probably needs to be either dead-ended or
combined with one of the other wires but have no idea which.
The little electrical knowledge I have was acquired in the UK where
the wiring conventions are different in terms of colour-coding though
I will admit to having been baffled by 2-way switches there also.
I just need to know what the combinations should be in the light
fitting and in the switch for simple one-way operation.
Thanks in advance for any help.....

In the US, White is (almost) always the "Neutral" or Grounded
conductor. Not the Ground wire, but a Grounded/current carrying
conductor.
Black and Red may be Hot (120V to the White wire) or might be
switched Hot.
What I don't understand is where the power is originating in
your scheme. IOW, how are Blk and Red becoming Hot?

Or perhaps Blk,Red,Wh do *not* simply go from one box to the
other; there may be an intermediate box supplying power.
