I just want to ask a noob question here, why don't car manufacturers use LED lights as standard out of the factory? Is it because the LEDs are significantly more expensive than the traditional bulbs?

So we could have interesting reads like these.

I honestly think it's because car manufacturers are perpetually 10 years behind the rest of the tech industry. They sold new cars with cassette players until very recently. They still think CD players are essential. I bought my last CD before they started putting CD players in new cars.
So LED lamps and customizable touch screens will replace bulbs and dials. Within the next decade or so, after we started to see them as old and quaint.

I would think it has to do with production and warranty cost.

Look at your tailights...they're LEDs. Auto mfgr's have increasingly used LEDs in recent years, commonly used in taillights, parking lights, accent lights, center brake lights, etc.

My '06 350Z had LED taillights.

Unfortunately, a modern car is designed as a system controlled in one way or another by a computer.

ETA: Zero interest in LED lighting. Are there kits/installs out there that just send you LED's and no supporting hardware?

My '15 Camry has LED DRL's and hi/low headlights from the factory. They throw a more focused, controlled, penetrating beam in all weather than any headlights I've ever used including HID's and high powered off-road incandescents.

Adoption should spread throughout the industry pretty quickly given their low power requirements and manufacturer's trying to squeeze mileage ratings in any way possible to comply with onerous new CAFE regs.

Plus they do have a distinctive look common to high-dollar EU imports until you get closer and realize it's a Kia.

That's exactly where my wonder came from, most cars now come equipped with LEDs in the headlight & taillight section, but not for the interior lights or license plates. So I suspect the reason they didn't switch to all LEDs completely might be due to production cost. But I am not in the industry, so I am not sure.

True, LED's currently cost more than incandescents.

I think the gradual fleet switch to all-LED's is mostly for style and somewhat a desire for owners to duplicate the CAFE numbers. The tests are conducted with electrics off except for climate control. City cycle especially benefits from LED's where alternator drag has a greater relative effect than highway numbers that are affected more by wind drag.

which fuses are you checking? im having same issue gauge thinks high beams are on.. and the lights wont turn off with key out.. I removed the BIU and dont see anything physically burnt..

Even some light modules and door switches are tied into the OBD computer system.

And if you want help, learn some manners.
I would have gladly helped you out, but based on your comments I think you're just a *&^%&.

You couldn't be more correct

DRLs, headlight auto on timing etc are tied into the OBD system as well and I only know this after using a Bluetooth obdII dongle to disable the DRLs and seatbelt chimes through the ecu, who knows whatever else headlight related is connected to it

Remember the OED is a British publication.

Merriam Webster does show it as a chiefly British word.

As it stands, One for One, LEDs cannot beat HIDs in terms of light output. The Camry LED headlights are cool but watt for watt, a HID setup in a comparable housing will outshine it.

I'm not doubting it throws a more focused, controlled, penetrating beam in all weather than any other headlights you've owned... but what headlights have you owned to compare the Camry ones to? I'm intrigued. For the record, I love my LED DRLs.

Subjective tastes and sentiments aside, it's a matter of Optics.. Actinology scientists and professionals will chime in and offer their perspectives as well. @Diode Dynamics want to offer some insights? I know ya'll recently did an LED/Halo/HID comparison for Low beams in the FR-S/BRZ stock housings using industry standard testing equipment. This will not be completely true to the case at hand because it is not an LED housing, but still it offers some cool perspectives and findings.

Lexus IS and LS HID's, Toyota Prius HID's, Toyota Camry/Highlander/4Runner/Tundra/Sequoia/Land Cruiser/FJ Cruiser incandescents and projectors, Scion FR-S HID's.

Maybe it's the temp of the light, optics, reflectors, who knows, but on an unlit mountain road in rain spray I'm glad to have LED's.

I won't count mega off-road driving lights since they're illegal on road.

But when you say "watt for watt", don't LED's use less power for a given light output? If so, would equivalent wattage LED/HID bulbs still favor HID's?
