Ok, so new switch, filter and oil and all good now 😀

So far from what I have seen, it's always the switch.

That's not definitive as more than one item was changed, and always complacency to assume its the switch. Leaves open the opportunity to ruin bearings etc if the assumption is wrong.

I wasn't assuming anything. All I said was: So far from what I have seen, it's always the switch. Doesn't mean much, but some could welcome that as a recommendation: look there first, before you do the complicated stuff like diving in the engine.

Here the answer from Germany.
Osram und Philips bieten zugelassene LED H7 aber auch H4 an. Du darfts sie aber nur nachrüsten wenn sie für das Fahrzeug auch geprüft und zugelassen sind.
Für die Hondas wird das wohl nicht der Fall sein.
So, you can only fit them, if they've been tested and admitted for your specific vehicle. That's also what the article said.

Personally I wouldn't fit anything that could possibly lead to annoyance like blinded oncomers. I was raised with the proverb: what you do not want done to you, do not do to others.

I have the 3000k warm white LED. Hopefully the morons on the roads will see me with a yellow(ish) light if the data is to be believed.

Interesting, I'm sure there was a time in France when everyone there had to have yellow headlights, I don't know if EU law up ended all that or they had new ideas about it?

Unfortunately the yellow lights, allthough streetlegal, are becoming more and more extinct, due to EU laws which (uniformity for carmakers). It's a pity. They were better noticed in bad weather conditions like fog and snow. Also there was hardly any blinding of oncomers.
As far as what's mentioned above (UK ruling) in the EU fitting a LED bulb in a standard or H4 reflector is not streetlegal. Leds only in reflectors for Leds, halogen H4 only in H4 reflectors.

Tried and tested by a forum member, hardly unknown!

Tested for how long? Did he have a look at the inside, the wires, the quality of the isolation in there?
If a coil is of a known brand, you can buy it, even when made in P.R.C but... if it's a non brand and made in P.R.C, look elswehere. My advice.

First, I hope you all enjoy your cheap generic coils of unknown quality and further...

[...]
If the coils are connected the wrong way round the bike will run but the HT spark will be reversed so instead of jumping from the centre spark plug tip to earth the spark path is reversed. {...}

To put it simple: in a wasted spark system, one of the two, is already jumping from ground to center electrode, so if the spark of say #1 plug becomes reversed, than the #4 plug will be reversed the other way around, because they are one circuit. For the running of the engine, it makes no difference which of the two fires from ground to center electrode: performance is the same. 

Usually the lens will have 'H4' in the center of the glass, if the reflector is fit for halogen bulbs.
The socalled 'charging shortcoming' of the these bikes is an urban myth. I've had a 55/60 Watts bulb all those years - my model came standard with it! - and never had a problem, not even with 3 Ohms coils and a transistor ignition. Every ride I return to the garage with a better charged battery than I took of with. 44 years of experience here. I recommend Philips. The Extreme Vision Moto H4 and Osram Nightbreaker came out best in tests and that Philips was especially developed for motorcycles and can cope with vibrations up to 10G.

Those are EBC FA13. I had them decades ago and replaced them soon thereafter (pic). They sqeal like a pig. Also you need to remove paint from the sides and chamfer them somewhat.
I now have SBS Street Organic 501HF. Mwah... ok, but nothing special.
