I seems like there are a lot of requests in the form of "What's the best currently-available bulb in my needed format?"
Yes, but sometimes those requests require us to ask the OP what they are driving, the condition of their headlamps, their preference for longer life (when bulbs are so difficult to change the dealer has to do it) or better performance, or any other number of things.
Seems like a good idea for a sticky, to be maintained and updated by the mods.
And it'd be a lot of maintenance! Improvements can come at any time, and a particular model could suddenly fall into disrepute if the maker suddenly starts doing things like heavily tinting the glass, or takes shortcuts in manufacture to the point that it's not "a bad run", rather it's "from here on out", etc.
We could probably build a guideline sticky, but for the most part that could result in people coming in, picking the bulb that is "the best" and going away, and never addressing issues like aim or lens condition-- even if it's in that very sticky!
