In the "LED bulbs vs LED headlights" discussion I found the below test quite informative... net net be very careful with H4 LED bulb replacement selection if you want to (risk?) that route...
https://www.autobulbsdirect.co.uk/blog/are-led-headlight-bulbs-the-brightest/ Main question for those going for the (car*) LED headlight is... what do you do when you travel abroad and need to change the dip direction or mask the headlight? (* AFAIK bike headlights don't do a directional dip, but are not car-legal... )
