Lights on all the time

[Graham53]

What's the under seat code and where is it ( as I'm typing it I'm realising that it's a foccing stupid question and feel like a nob but I had to ask ?
However further to the original post I was starting up and lights came on then turned engine off using kill switch but lights stayed on which I now gather is correct but if I turn ignition off then back on the side lights only come on until starting then dipped beam comes on so I may have mistaken that for the lights staying on when the engine was not running.
thanks
