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?
