Vstar has a conventional headlight shell I think.
There are LED bulbs without fans or outside heat sinks.

Do not know why that posted before complete.
There are ribbon, fan and fanless LEDs.
Some use "control boxes" some do not.
superbrightleds.com and advmonster.com have good reputations and can be helpful.
Advrider has several threads on Evitek (sp?) old and new version bulbs.
I looked at Ironwalls H4on e*** after finding recommendations. About $26 no boxes.
Then decided to go fanless with a $19 h4 ($18.96) e*** set. Recommended on FZ1OA forum. Putting bike away so haven't ridden with these yet. They do have "boxes."

advmonster.com Native H4 is easiest mounted one $37 single bulb


There are a number of "sealed beam" type inserts headlights with multiple LEDs
