Toyota Corolla Headlight Assembly Dissection

[@RD-qp3mu]

Glad to see it can be taken apart. Well done, and thanks for showing us the geeky bits.

[@Nick41622]

I suffered from wrist drop three weeks ago, which prevents me from doing a thumbs up gesture. However, I can still give you a thumbs up.👍

[@jamesemanner9671]

MY kind of technician!!! During my many years of maintaining IBM computer mainframes, always disassembled failed assemblies to analyze the cause.

[@russtaylor385]

You awakened my inner geek with this Peter. Loved it!

[@mikecorrado4971]

This was a fascinating video! I am disappointed with Toyota for making a headlight assembly in which the low beam cannot be accessed. To me, this is an engineering boondoggle! Thanks for a great video.

[@billp4]

Not to mention putting computers in the headlights?

[@Wambamdoozle]

The only way to make led headlights lights reliable is to seal it from the elements, put a giant heatsink on it and use a flux led. Consider how much goes into that low beam shell vs an aftermarket led bulb. They have all the same components but the Toyota one is built like a tank

[@LAactor]

Yes it's a sickness but only for non mechanics. For mechanics they are life savers when you have your own inventory in stock for a broken or missing part. A used OE part is better than a broken part. And definitely better than a missing one. Fasteners are expensive and they add up!!

[@emehlhar]

Sometimes, it's better just to stick to tried and cheaper tech like halogen bulbs. My 89 uses a $10 headlight bulb that I've only had to change about every ten years.

[@wolfeadventures]

Not nearly as bright. So it’s better in one sense-cost, no other.

[@derek2479]

Great video, thanks! 2014 Corolla owner. I figured that there was some lenses and magnification shenanigans going on to make a tiny LED shine so intensely, and this breakdown answered my question. I'm going to guess it needs such a huge heat sink because the assembly with the LED is (supposed to be) completely sealed. No air cooling. Even though LEDs don't throw much heat, it could get pretty hot in there.

[@Jeff_C_2112]

Thanks for dissection Petr - great job!

[@agostinodibella9939]

I don’t understand why they had to put the electronic computer part inside the headlight instead of under the hood? I still remember the good old days when you could buy a new headlight for less than $10.00.

[@hlq2action310]

The good days are gone.

[@jameswhite1319]

Thanks for sharing Texas

[@seanpop2886]

A $1200 10-year/100k service agreement from Midwest Toyota in Kansas is an even a better deal with difficult-to-replace headlights. All the computerized stuff is justification enough for the VSA.

[@konradhittner4668]

As impressively complex as that headlight assembly is, a complete, lifetime-warranty replacement (Toyocera, a very high-quality Taiwanese aftermarket producer) is $144 at RockAuto. But your dealer’s finance manager does thank you for spending your “peace-of-mind” dollars with them.

[@bblod4896]

The headlight power module can be repaired. It looks as though there is conformal coating on the PC board. That coating protects the board and components from moisture. Thanks for the video.

[@Shododaan]

I wish my two lexus cars had headlight lenses that came off that easy! Great video thanks for sharing it =)

[@camaro84rules]

that was fun, thanks for taking that apart!!!

[@markreynolds3850]

Thanks Peter, awesome video, interesting info.👍👍

[@Jimmyky77]

Did you find the area of the water Intrusion Peter? And are you going to reseal the headlight assembly with some automatic silicone sealer or equivalent? Thx for sharing 👍🏻

[@jimcharb4230]

The light looks like the Martian eye from War of the Worlds.

[@daphlavor]

I wanted LED lights on my 2016 Sienna but halogen lights came standard, interestingly enough my headlight assembly looks identical to this minus the driver electronics, I upgraded the bulbs to aftermarket LED for most of the lights, including a white/ yellow fog set up. I’m happy with my setup, especially now after seeing what the price of this was.

[@michaelbrennan7148]

Happy St. Patricks Day Peter 🍀. To you and your subscribers Golden Road California!!

[@davinp]

The Toyota Corolla was the first compact sedan to use LED headlights. The Honda Civic still used Halgeon headlights

[@Nick41622]

I see you all over KZbin.👍

[@RockyMtnguy01]

Wow the engineering compared to the old sealed beam lights!

[@negativeindustrial]

I’m finally going to convert my 1990 MR2 Turbo. Sealed beams are for the birds. Especially with an aggressively raked sportscar.

[@baitergaming2101]

Can you make maintenance video for Lexus ES300H? And what is your opinion on Lexus ES300H?

[@davinp]

Toyota update the headlight for the 2017 model year. The S became SE and has both low and high beam light or dual lights. While the LE has only a single light

[@OkechukwuOnwe]

Thanks for the good work, is 2008 Toyota Corolla a good car to buy used?;l can't afford to buy the newer models.

[@davida871]

9th generation ended 2008 so without question one of the best to buy for reliability and longevity.

[@OkechukwuOnwe]

@@davida871 thanks a lot.

[@johnaclark1]

They are excellent vehicles. I own two of them. I also own a 2009 Corolla but it's nowhere near as good a car as the 2003-2008 Corolla.

[@charlesmielke9859]

Love the video. Thanks for sharing.

[@dmarsden1324]

I have a hi tech way of preventing this moisture from building up in this enclosure. Drill a smallish hole in the bottom, and if you can another hole in a sheltered position above it. This will enable the light to drain and dry with the heat of the led. Really hi tech but it works.

[@michaelbrennan7148]

Thank you Peter

[@wingtsang7354]

Correct me if I’m wrong but you should not be able to remove the cover like that without heating up the Butyl rubber that seals the lens to the headlight assembly. 🤷🏻‍♂️

[@livincincy4498]

I have to ask myself is all this irreplaceable technology worth it ? A bulb is pretty easy to replace. This is a $500 part plus labor to order the part, remove and replace. So what $1,000 repair? Never should have gotten rid of my 1970 VW bug…

[@BRIGGS2710]

a used part + diy, would likely be $150

[@jlow4214]

Now I know what the thing that blinds me whenever met at an incline and oncoming looks like!

[@williamtukeyjr3661]

Never knew you also had the surgical skills too

[@christopherclark4774]

Hello. I have a 2001 Sequoia with 2UZ motor. In your opinion is about 205 ish degrees too hot for engine coolant going about 70 on highway with air conditioning on full? The dash gauge stays in the middle, but i have scan tool attached so I can see actual temperature. Thank You for your time.

[@joedominick7517]

Another interesting video!

[@harryl7946]

1:42 I think 🤔 you mean an ME. Medical examiner of the dead. 😵 a little more like Quincy, ME 😂😂😂

[@anyheck]

I found a parts diagram for the led driver in the Japanese version that shows a removable panel at the bottom of the assembly. The drive part is unfortunately about $420 so little savings there, but easier to open than removing the lens.

[@JarrodAllenSmith]

Is this different on the 2017?

[@N1WP]

Cool, or you can hook it to the same voltage source and have a cool lamp!

[@livincincy4498]

Thanks !

[@KendrasEdge757]

Made in china 🇨🇳 that’s the problem with this Toyota japan 🇯🇵 oem light 😂

[@19910602011]

On my 2015 Toyota corolla Altis my headlight is the same way on the elegance model but the base model have replaceable low beams

[@seanh2390]

interesting!

[@pbr549]

Seems to me this is a complex solution for a low beam head light. Toyota needs to use a bulb and develope plastic lens that don’t fade or try glass. Just saying.

[@SoumenMittra]

If this was just water damage and possible to fix by drying out the equipment they why didn’t you give that option to the customer. Wouldn’t it be cheaper than buying a new headlight assembly. Did you acquire consent from your customer to keep the old equipment. In many states it is a law to allow customers to keep the replaced parts.

[@geoffwalker7530]

So much complication and expense and end result is drivers complaining about being dazzled and generally lights being way too bright. There was never a problem with simple halogen or even tungsten bulbs so lighting has made negative progress in 40 years

[@johns6816]

What Crap! So a simple broken headlight assembly is $500? Conservative frugal hard working folks drive Corollas because they are economical. So maybe Toyota is not such a thoughtful manufacturer after all. This is no better than some of Ford's BS.

[@hokie9910]

It’s better, a lot better. Take this Corolla and run it 250k miles….I bet it’s total repair bills are a fraction of any Ford, GM, or Stellantis product made today.

[@AudiophileTommy]

Plastic headlight assemblies are 🎉CRAP 🎉🎉🎉🎉🎉

[@LAWRENCEFLANAGAN-g2i]

So ,why did it fail,would a smoke test have found it?.

[@Nick41622]

But the lens can cost more than the whole unit.

[@kenk3102]

...totally over-engineered....seriously!...it takes a COMPUTER to turn a headlight on and off!...wow... must have some really bored engineers at Toyota...SMH... 🙂

[@condor5635]

This is the sort of technology that just pisses me off. Hundreds, if not thousands of dollars. When all I want is a lightbulb and a harness. Simple to replace and cheap. All this fancy LED stuff just a waste of money and time. For what?

[@3800TURBO]

Talk about being over complicated for no real good reason..

[@robertblacksmith4355]

My truck uses "Sealed beam Halogen" glass $40..

[@seamasrigh2162]

So, the low beam "bulb" is $500. Toyota quality? I love my Toyotas; but they use real light bulbs not the integrated LED garbage that cannot be repaired, only replaced. Come on Toyota don't go down GM's road.

[@peterferree4033]

Can't quite place the fake accent ...🤔
