Meh, it states quote "This type of headlamp, halogen reflector, only supports night-time driving (low beam) on unlit roadways at speeds up to 39 miles per hour, when in new condition." I get it, they're regurgitating what someone else spec'd about how much light you need to be *safe*, but I call it nonsense. Of all road hazard and accident causes, inability to see further just isn't usually one of them unless it's heavily raining or foggy, or the problem was the opposite, that someone blinded you with their LED retrofit drop-in headlights.
I've been driving all my life, safely, at 40+MPH using low beams. If there is low traffic, and lots of curves and hills (common around here) I'll switch my high beams on, but remember they are talking about NEW condition. I have no problem going 40MPH with low beams in DIY restored condition for 90% of my night time driving...
... but I don't have a 2007 Malibu or Altima, the only two samples they bothered to test.
That said, my '98 spent a lot of time in a garage instead of direct sunlight so they were never as bad as the used ones shown in that linked article, and the TYC replacements at $22 are a great value. We're fortunate that the assembly isn't more complex and integrated. 5th gen headlight housings cost $350++.
