Look at the graph and read the summary below the graph again. The LED headlights were rated poor due to excessive glare and because illumination was inadequate on both left curves and on the left side of the road on straightaways.The LED headlights were rated poor due to excessive glare. The illumination they provide is very good (too good?) as evidenced by the illumination distance graphic.
This is very evident when driving on a non-illuminated road at night that is lined with trees. You will see weird "light sprites" appear all around high up on the trees, like little streaks of light to the sides. It seems like the design of the reflectors leak light in undesired directions causing glare to oncoming traffic and the poor rating from IIHS.
Excessive glare can't be understated. It's arguably more of a danger since it can dazzle multiple, oncoming drivers. Inadequate illumination primarily puts only the driver at risk of running into something they can't see. The lesser of the two evils is inadequate illumination.
The Ridgeline/Pilot's LED projector (low beam - the high beams are halogen reflectors) headlights have slightly better illumination levels than the Civic's LED headlights, but never exceeded glare limits. They received the highest possible rating of "good" - the only pickup to receive that rating. Ironically, I get flashed in my Ridgeline frequently even though the headlights are perfectly aligned.
The Corolla's LED projector headlights received the second-highest rating of "acceptable" with no excessive glare.
If you look at ratings of various LED headlights, it looks like those with projector housings have a higher overall rating and less glare than those in reflector housings.
