Here's a long discussion thread

Headlight LED -- F2 vs F3 vs NB35 | Lighting / Visibility

There are LED bulbs that have more power than the F2 LED bulb. F2 is 33 watts. F3 is 44 watts. NB35 is 44 watts. They both produce 33% more power than the F2. So they are brighter but.... You cannot compare these by which has the highest peak brightness. The F2 and the F3 have about the same...

LED bulb. F2, F3 or F3 with an F2 sheild. Many of us have them.

f2 - best https://www.amazon.com/KATANA-H4-9003-Headlight-Bulbs/dp/B07JM421VC?th=1

or f3 - a bit brighter https://www.amazon.com/Alla-Lighting-Conversion-Replacement-Motorcycles/dp/B07T8SDCBB

or f3 leds with f2 shield. The one I recommend to others at the moment. https://www.amazon.com/Cougar-Motor-H4-Headlight-Conversion/dp/B082MDGVDC?th=1

Just make sure you get the H4 plug end.

In europe, there are now road-legal LED's H7 from Philips. They have CE approval.. I really like them..

How do you connect an H7 bulb to an H4 connector, or do European bikes have a different connector than NA bikes?
 
EU bikes have the H4 connector. H7's might be possible to physically fit, but are only single filament I believe?

LED bulbs (in incandescent housings) are still technically not road legal at all in the UK, but the DfT appears to be experimenting - they've told our annual roadworthyness testers that they should not fail motorcycles with LED bulbs so long as the beam pattern and brightness still otherwise complies. :) Mine passed with F2s fitted a couple days ago.
