don't exist - BM and Merc use a system that even the latest 2023s bulb from the high end LED kids with canbus fake it electronics still can't cope with - (and yes I'm using novsight - half the time it turns itself off and may or may not choose to work again with key on off reset and I get two different headlamp codes !!! ), best way is to add a load resistor to bring up the load so the bike doesn't know any better - there are posh ones and nasty ones... but they all look to large to fit in the old air cooled lamp unit
also the re is no mask on the BMW lamp unit so its quite dangerous for other road users - her ford electronic doesn't have any issues (as they don't employ the design to muddle checking the german's love - and back then novsight did 6000k - and they are much better bulbs than the current stuff
as for latest rubbish you need 5000k white so the retards make 6500k blue as the only choice thus u go up the road like some welding spark with so much blue light its not helping anyway near what it could
roughly
halogen yellow dim glow worms are 3000k
what we thought was white bright OEM xenon's, started life in 1999 as 4200k
by 2010 many moved to 4700k
and then LED came in and burnt out your eyeballs - I guess with OEM cars at 5200k
NOTHING above 2700k will work in heavy fog - so clearly they want everyone to crash and die... anyone remember the legally mandated yellow headlamps France used to have - and no one needs more than 5200 as after this colour temp its going back in the wrong direction making it worse....
