I replaced every replaceable light on the bike with LEDs long ago. But the way I figure it if I want to run full electric clothing, plus other equipment, it won't put a strain on the system. An electron saved is an electron earned!😜
I used to do self deprecating humor, but I wasn't very good at it.

I like the 1 light system because it can save more electrons for other uses, such as heated clothing, etc.

i checked with multimeter - 2 lights do not take any more power than 1 light

Note:

As we have a shunt type regulator / rectifier on all V1k the alternator outputs 100% power all the time when above ~ 2500 rpm

Any unused power is dumped back into the alternator in the form of excess heat.

So if you save too much you could in hot climates possibly overheat / burn out the stator coils, but as the stator is oiled cooled, if you keep the oil level at the upper level mark it can cool the stator better  :028:

That is also why the alternator cover is always hotter than the clutch cover 😎

Bull Feathers! I've heard some silly things on this forum... But that takes the cake.

What setting did you use to check ....if you truly saw no increase in power usage with 2 bulbs over 1, your meter is broken.

I went all LED to save a few watts for my heated gear..... probably not the most economical way  but its works..:)

Not a very sophisticated multimeter. but good enough to see if there is a significant difference between one beam and two beams' power consumption.  the alternator is probably compensating for such a small difference.  I have too, LED bulbs.

when on idling, the battery was 14.80 V with one light, and with 2 was 14.80 as well.  but when turning on the Denali D7, it dropped to 13.50.  in the picture, it is Versys 650 with Denali Dm, and lower is D4, by the way.
