How they measuring it?

If they were truly inadequate they wouldn’t be DOT approved.

 

DOT/FMVSS 108 certification of headlamps stipulates that they "meet luminous intensity maxima and minima that are specified at fixed horizontal and vertical angles relative to the central axis of the headlamp", as well glare intensity maxima.

 

In real world driving, DOT approval does not mean that the headlamps provide adequate visibility performance for drivers, nor does it ensure absolute maximum glare limits. The loose nature of the FMVSS 108 standards for headlamps on U.S. market cars and light trucks means that there will be significant variation in visibility performance as well as glare metrics. That's exactly what IIHS' data shows.

 

Refer to the rationale and supporting work document from IIHS linked in the previous post for more information.

And since they are the sole arbiter of the rules that they follow, they will change them once criteria they set is met. Just to keep themselves relevant.  

 

Its just like crash testing-a car built in the past 20-30 years is just as good as one currently in production in the vast majority of accidents. There is a point that physics can't be overcome.

 

We often joke when they are going to implement a sharpened metal object and require a windshield to deflect it.

Which makes them perfectly adequate.  Maybe you should look up the definition of adequate.

No sir. Maybe you should read the documents IIHS wrote on its headlight testing protocol and supporting work.

I dont have a problem with IIHS, just insurance companies in general

I don't recall where I saw it online, but there was a report about the government changing headlamp standards, etc. 

 

Yeah, apparently the infrastructure bill finally paved the way for that standard to be updated.

They’re finally reviewing the standards to bring them up to date and hopefully allow more of the European style systems.  Canada is also considering making automatic headlamps standard and requiring the instrument cluster not light up if the headlamps are off.

 

Maybe they should have the cluster turn OFF at night (remain on during the day) when it detects it's dark.  Or just autolamps default as pointed out.

You mean like the 2021 Ford Bronco (and possibly other Ford vehicles):

 

 

I didn't realize they defaulted to auto.  That's interesting.

Glad to hear that you made it home safe (whether due to a Christmas miracle or otherwise), but there's still no excuse for automakers to equip new and redesigned cars and light trucks with crappy inadequate headlamps, like Ford did with the halogen units on 2021 F-150.

 

 

"Inadequate" by whatever standards they make up.  And like these offset test, they'll just shift the goalpost more at a later date.

The standards come from CIE Report No. 188, UMTRI, and AASHTO. Refer to the IIHS Supporting Work document for details.

 

Visual examples of adequate (LED) vs. inadequate (halogen) low beam headlamps on 2021 Hyundai Kona in actual real-world testing, environments identical for both. Both sets of headlamps are "DOT approved".

Adequate (For comparison, 2021 Bronco Sport LED low beams provided similar performance).

 

Inadequate (For comparison, 2021 Ford F-150 halogen low beams were even worse than this).

And I'm sure last year the "inadequate" F-150 lights were "adequate", but the goalposts were moved.

 

I'm not saying improvements in tech/standards are bad, just that changing the testing procedure doesn't make last year's model suddenly a death trap.

Why can we be told our washer tank is low and we cannot have a warning pop up on the dash saying "your lights are off and it is dark you dumbass."  Rental car companies almost across the board turn off the headlights and customer's don't even realize they are running around town without their lights on.....very dangerous. 

I know some GM cars like Cadillac would have a message come across the dash as “headlamps suggested” if the auto lamps where not on and it was dark out. That was in the 90s and 2000s. Cadillac for sure did it, my folks STS and Deville did it. Not sure about other lines.
