Try as I might, I can't find how CR tests its headlamps exactly.
https://www.consumerreports.org/headlights/how-consumer-reports-tests-car-headlights/
All I can discern from the above link is that they aim the lights and drive around on a track with "specialists." The whole ordeal seems to be subjective since it's always talking about how "specialists" rate glare and "cutoff" and "reach" and "intensity" and the such.
And from what I've read on CPF, people here have a dim view of CR's headlamp testing methodology. But no one really specifies a weakness, apart from the fact that their testing methodology was developed by engineers at Guide, which apparently made crappy lights for GM. And then I read something about how CR prefers lights with no cutoff, and that was perhaps the only concrete criticism against CR's testing methodology.
Is there a published testing methodology out there somewhere for Consumer Reports? Does anyone have any more specifics on what they do?
