Either way, it never hurts to replace old wires or connectors, or use new tech such as leds. If it helps with battery charging, well that's just a nice side effect.
  But... it does hurt when the investment doesn't pay of, has been unnecessary, read: the expectations one had, have not materialised in practice, but just a fraction.
But hey, you've had your happy moments going the D.O.U cycle and 'caring' for you bike. Whether that 'caring' has been any more rational than a little girl nursing her doll...

No, it won't hurt. A decent led bulb is brighter than the typical turn/brake bulbs. That is a measurable safety factor, and is never a waste.
Brighter does not equal more safety. I have posted numerous times on why the old style omnidirectional bulbs are better noticed, also thanks to their flare up and flare down. Led is not as lively as the old bulb and draws less attention, in spite of its brightness, which btw is only unidirectional. That's why more and more German carmakers have 'walking' led lights for indicators, to address this shortcoming and create more liveliness.  Good luck in realising that on your bike.
New wires and connectors are never a waste as sooner or later, old connectors and wires fail, no matter what.
Why not wait till later, when a V drop test might indicate a loss. Are you suggesting I should clean or replace my wiring in spite a V-drop test shows nothing is wrong there? Do you think I have nothing else to do?
And led headlight can be argued to a small extent. Depending on the housing it is in and if it can be adjusted(many can now), it may or may not be brighter. Though it usually is. Therefore, also not a waste. Put an hid in my 750, adjusted it properly, and it works spectacularly.
Here we go again. It is exactly what the advertisements want you to do: interpret brightness in lumens as quality.
The quality of a good headlight is not necessarily in brightness. Beam pattern, street legality come first. There is see and be seen. For being noticed, research has shown, bikers are better noticed with a yellow(ish) headlight. Can you give us results of tests, carried out by indepedent bodies like the AA, ANWB or ADAC that substantiate any of your claims? Any measurements on the performance in Lux, for instance, instead of meaningless talk about brightness in lumens? Anything by professionals, in stead of biased talk after you've done purchasing? Ever heard of cognitive dissonance? Any idea why bikers choose to replace the stock by a yellow headlight for their safety? What do you know, that they don't?

But when?  Wiring on 70s bikes may still be fine.
My neighbour in a semi is on his third complete roof because he worries that it may leak. We get someone to check the tiles every couple of years and it's the 1938 original. (apart from the few odd tiles he replaces)
Maybe orange is available.

A proper diagnosis should come first. Apart from issues (multiple!) with sparkplug caps, I have not encountered other electrical problems than the IGN key switch and the fuse ends and clamps that needed to be cleaned. The latter I had to do, when on a trip in the German Schwarzwald (Black Forest), one fuse after the other blew. Connectors headlamp are spotless. No wonder: the mere replacing of the bulb a couple of times will already clean the contacts. BTW, a simple V-drop measurement can locate a problem easily. IMO you learn more from doing such a test to arrive at a pinpoint diagnose, than parrot others and replace just all. Why not invest in yourself and trust your insight?

Delta, I see once again, you only read what you want. If you bothered to read it all, I DO mention beam control, ect. Not just brightness. Bright is no good if it scatters, I've said this in the past, as well.
All things being equal, a brighter light is still safer, especially compared to some crappy yellow. Further vision at night is never a bad thing, and being able to see ditched better is also never a bad thing. At this point, you are being deliberately obtuse, to pretty much everyone here.

When something fails, when does it usually happen? Maybe you have excellent luck, but for me and most people I know, things fail at bad times. It's partly why we do maintenance anyways, right. To prevent possible problems. Obviously, we can't prevent everything. I mean, you don't wait for a tire to blow out. A person doesn't wait till the engine seizes to change oil. You get what I am saying.

timtune: Have you thought of red?

Yeah but who wants the second fastest colour?
Seriously, is there an easy way to get red? I've opened a huge can of worms here and all I got (or at least took away) was "fancy coils bad" "new H/t leads hard"

You can get Dyna Coils, as the leads are replaceable you can use any colour (color) leads that you want.

I had red wires back in the 80"s.
Stock coils. Cut the stock leads ca: 2.5cm from the coil. Crimped the new red together with the old short black. A few layers of crimp hose over the crimped socket.

Bike got 5 ohm Dyna coils 2014.
Dyna coils have auto fittings for H/T leads that can fall out. When power wash or something that xan whip the longer leads. 
Std copper wire with not that soft insulation make them to sit better. I had some issues with a lead coming off, cyl 1 especially. Maybe 4 too. The longer leads.

The harder type sit better.  Both 1 and 4 leads strapped to frame  between coil and plugs.

Below red leads on stock coils.
