Cheers gents,
Might have a diff main switch Bitsa... I've just deleted the 'crappy switch', and now have park lights on with ignition, and then as you say, low (middle position) & Hi right position.
MOT today (pass - yahoo!) guys didn't comment - a first - so it must be good.
And with that, reckon I'll leave it this way... esp as generally stick to daytime only.
Thanks again,
Simon.
