Apparently, the aftermarket bulbs are the correct dimensions, but we all know that just because its the right size doesn't mean it necessarily does the job properly.

having had a cadre of "yute" engineers who were constantly modding their cars, several of your words above ring true: "...many aftermarket solutions fall short."
