A GMC Hummer EV taillight costs an eye-watering $6,100 to replace, plus labor. The idea of having to replace one of Audi’s new adaptive Matrix LED headlight setups is something most people probably don’t want to stomach.

Audi made these adaptive light strips to fix the artificial problem of newer headlights being too bright compared to older ones.

Meanwhile, only 30 years ago when we had sealed-beams in standardized shapes, you could replace a headlight for like $10. And the lens was actually glass instead of plastic prone to yellowing and abrasion.

[–] frongt@lemmy.zip 8 points 2 months ago (1 children)

Yeah and if you hit someone that glass shatters and stabs them. The plastic is shatter resistant.

[–] west2seven@lemmy.dbzer0.com 2 points 2 months ago (1 children)

Did you know shatter resistant glass exists? Like your windshield for example. The issue is plastic is cheap and easy to manufacture and nothing else.

[–] Summzashi@lemmy.world 2 points 2 months ago

Tempered glass is very hard to mold into a complex shape. Those plastic headlights shrouds are much cheaper to replace, it's the internals that are expensive.

Also that plastic you can just polish and they're like new.

They burned out and needed to be replaced. New ones should never burn out

[–] grue@lemmy.world 12 points 2 months ago* (last edited 2 months ago) (1 children)

You say that as if saving $10 on a bulb once every few years is worth the risk of spending $100s or apparently even $1000s if they get damaged.

There are reasons cars have been getting ever more unaffordable (above and beyond inflation), and stuff like bespoke model-specific headlights requiring complicated tooling to manufacture is one of them.

[–] AA5B@lemmy.world 2 points 2 months ago (3 children)

Cost wise, no it’s not worth it.

But you now have an item that

  • never needs to be maintained
  • is brighter
  • works better

The adaptive headlights in my car are truly amazing, and every time I’m blinded by oNcoming headlight glare I wish everyone had them

[–] deleted@lemmy.world 7 points 2 months ago (1 children)

They’re nice until you need to replace them.

[–] boonhet@sopuli.xyz 1 points 2 months ago

Unfortunately that's the fifth owner's problem so nobody really considers it

[–] scarabic@lemmy.world 1 points 2 months ago

I might support this point of view if the last 20 years of lifespan promises with new light bulb technology had actually been true.

[–] Soggy@lemmy.world 0 points 2 months ago (1 children)

Brighter is a negative trait in my opinion.

[–] AA5B@lemmy.world 1 points 2 months ago (1 children)

I partly agree, headlights are causing harm by blinding other drivers. But adaptive headlights seem to work. Brighter should only be allowed with adaptive headlights

I can drive through a busy area with “high beams” on but watch dark spots move to keep other cars in the dark

[–] Soggy@lemmy.world 1 points 2 months ago (1 children)

I live in a very hilly area, adaptive headlights do exactly fuck-all.

[–] AA5B@lemmy.world 1 points 2 months ago* (last edited 2 months ago)

True, you can never entirely take human responsibility out of the loop. And humans suck

Even when there scenarios adaptive headlight don’t cover, they’re much better overall than human

[–] kkj@lemmy.dbzer0.com 5 points 2 months ago* (last edited 2 months ago) (1 children)

So... put LEDs in the same form factor. Now you have lights that don't burn out and can be repaired. You can even use PWM to dim them.

[–] AA5B@lemmy.world 1 points 2 months ago (1 children)

Same form factor is the problem: LEDs need a different beam pattern with a sharp cutoff, otherwise they’re harming other drivers.

But adaptive headlights are even better. They seem to work really well and I’m a huge fan. I have really bright LED headlights so I can see everything but I can also watch them change to keep other cars in a dark spot so I don’t blind them.

The combination of super bright LEDs with adaptive headlights seem like a huge safety improvement for us all

[–] kkj@lemmy.dbzer0.com 0 points 2 months ago (1 children)

Same form factor doesn't mean same reflectors. It just needs to fit into the same space. You can fit LEDs into that space.

[–] AA5B@lemmy.world 1 points 2 months ago* (last edited 2 months ago) (1 children)

You could, but capitalism … most cars do not get aftermarket reflectors, no one would pay the significant cost, and LEDs fit into standard reflectors. There’s a whole bunch of failure here

[–] kkj@lemmy.dbzer0.com 1 points 2 months ago (1 children)

We're talking about the sealed headlights with the reflectors contained in them. LED versions have their own reflectors that could be (and I assume are) tuned to work correctly with LEDs.

[–] AA5B@lemmy.world 1 points 2 months ago* (last edited 2 months ago) (1 children)

I don’t think I’ve seen those since before my teenagers were born.

A few weeks ago I showed my younger kid how to replace headlights on his old car

The problem is you can find led replacements that fit the same base “for offroad use”

When to be legal, to not cause glare problems, someone would need to re-engineer the assembly and people would need to be willing to spend that kind of money

[–] kkj@lemmy.dbzer0.com 2 points 2 months ago

Yeah, it's that kind that produce disastrous results. Returning to sealed-beam lamps would solve that issue and make replacement much easier as well, but that would remove a profit opportunity for manufacturers, so it won't happen voluntarily.

[–] clif@lemmy.world 2 points 2 months ago (1 children)

By "artificial problem" you mean the problem that they created... Right?

... Right?

[–] badgermurphy@lemmy.world 2 points 2 months ago

He actually does mean that I think.

[–] scarabic@lemmy.world 1 points 2 months ago (1 children)

I thought we all agreed there is a problem with headlights these days? Is it just not because of LEDs specifically?

[–] XLE@piefed.social 0 points 2 months ago (1 children)

It's because they're made brighter and cooler than they need to be, basically. There's no reason they couldn't be less of either. We have Christmas tree bulbs made of LEDs that accurately mimic the old fashioned ones after all.

[–] scarabic@lemmy.world 1 points 2 months ago

Oh so you mean it’s an “artificial problem” as in they are “solving” a problem they created themselves. Not that there isn’t actually a problem.
