Yes, this should be identical.

I'm not entirely convinced that Triumph could have got away with
producing a car that did this when it was new. Short term, I can, as
you have done, simply set the idle at 850 with headlights,
radio-cassette, hazard lights and so on all running, but I am certain
that there is something I could tighten, loosen, repair or replace,
which would cure the problem. If I ever find it, I'll let you know!

I can accept that, but a 200 rpm drop just because the headlights are on
seems excessive to me. Thanks for the reassurance that I am not alone,
