Great to have such a forum, I'm just passing through

They are super bright and make you very visible in the daytime. Some quibble about the night beam, but it's the reflector that counts the most I think. Some people complain about anything. It works fine for me at night - but I don't do a lot of night riding. I haven't measured the amp draw, but have checked the charging system before and after, and it is fine, no discernable difference in voltage being returned to the battery at various RPM.

LEDs take a lot less current than incandescent. They run cool and heat = power draw. I would guess it's pulling less than the original. I also replaced all the small instrument bulbs so there's an improvement in visibility (neutral esp!) and less draw there as well. The headlight I got is quite good for $20, I run that bulb in my two '83 Suzuki GS1100E's. The GS1100E has the huge 9" 'train' headlight so it's quite the scene LOL.

This one is bright white, not obnoxious and not a blue tint like some. IMO you can't beat it for $20.

I confirm that led bulbs can be used without any problems, and it's even possible to install led bulbs without modification, which is what I did on my C72. The reference is Stanley A5676 12V.
As far as electrical power is concerned, by modifying the electrical circuit as shown below, I no longer have any worries about driving with the headlights on and using the starter without restriction.

The US version of the headlight is a sealed beam, it must be modified. I believe the Europeans had headlights with replaceable bulbs. That was the case on many vehicles back then.

Indeed, I had forgotten this American particularity .... that I never understood.
I had this on my 1000 Goldwing which comes from the USA and I decided to replace it with a European model because it's easier and cheaper to change a bulb than the whole thing.... if you can find one.

They didn't trust us with the intricacy of replacing bulbs. Whole headlights only. Baby steps.....

I'm curious about the LED H4. How well does it work as a headlight? Is the charging system able to keep up when it's in use?

Sorry, I missed this question. It all seemed fine back in the March timeframe, the charging system kept up with the added draw (40W or so?) - I rode it around quite a bit. But after a few months, the owner told me the battery was dying. I checked it out, and the regulator/rectifier - a nice, not cheap 'Charlie's Place' unit, wasn't giving enough voltage at the battery - only about 12.8V. It was 13.8V when I returned the bike to the owner, so hmmm. I put in a spare old reg/rec from a Suzuki GS that I tested out on the bike; it's doing 13.8V. I checked all the wires for corrosion, the alternator for output, etc. No problems. We shall see if it is something recurring. I don't see any issue with the setup, the Alternator is throwing 50V or so easily, and the reg/rec is doing its job. Puzzling.

The LED is very bright, makes the bike very visible in the daytime, and is fine at night on low beam and high. I couldn't ask for more. I will keep an eye on things and see how it goes with the new (old, really) reg/rec.
