On youtube i follow a bloke called the missenden flyer and he recently did a vid about the 899 headlights being much more yellow in colour than the running lights, i never really noticed this before but i just couldnt 'unsee' it, even the lights relected on vehicles in front at lights was irking me, so i swapped the bulbs and im rather chuffed with the difference..... Before..... During..... After. The bulbs i used where philips diamond vision h11 5000k.
Nop it's a bit fiddly but simple enough. Get someone with small hands to help you and you can watch and criticize.
Nothing to do with lamps (bulbs are for gardeners) but my missus has tiny hands, she makes everything look massuvive, if you know what I mean
