Size:9012/HIR2 Flip-Chip LED YOSAKY K4 Series features the new patented Flip-Chip (FC) technology which outperforms both CSP and COB in terms of light pattern and durability. Unique Light Converging Lens The K4 Series features light converging lens which make lighting much more effective. As a result, the K4 Series headlight bulbs with 6000LM are even brighter than some 8000LM ones. Specifications Input Voltage: DC 12-24V Power: 60W (30W/Bulb) Lumen: 6000LM (3000LM/Bulb) CCT: 6000K Luminous Efficiency: 100LM/W This configuration, while satisfies the lighting needs, won’t cause glare to the drivers and pedestrians from the opposite direction, which ultimately ensures driving safety. The K4 Series maintains 100LM/W to deliver the best durability as excessive luminous efficiency will cause overheat which has a severe negative impact on product durability. External Powering External powering can provide stable electric current, eliminates the flicker, reduce heat generated, and lower the working temperature thereby improve light bulb durability. Fan and Alloy Heat Sink LED light bulb product durability and the working temperature has a correlation. In addition to externalizing the powering, fans with a maximum speed of 12,000RPM have been installed on the alloy heat sink to improve heat dissipation. Certification The K4 Series headlight bulbs are approved by Department of Transportation (DOT) and legal in the United States. Warranty The product can provide 50,000 hours of use. We offer 18 months warranty period for every K4 Series product. Bulb Position The product is fit for 9012/HIR2 headlight bulb as high or low beam or fog light. Easy Installation Plug and Play. 1:1 halogen design, no modification on headlight housing or cover is necessary.

Best LED headlight bulbs compared to the ones I’ve bought so far
I’ve shopped a lot of LED headlight bulbs on both eBay and Amazon, the kind of Halogen, HID etc. So far, I find Yosaky most satisfactory. I am going to do a comparison of this brand verses some others I have tried before. By the way, I have a 1998 Honda Civic EX. Pros:-- Brightness. Among the headlight bulbs I have tried on my car, halogen ones are the dimmest ones, and then LED. HID ones are the brightest. I was kinda surprised of see this Yosaky pair I bought as bright as the HID ones, even though it says on the package 6000LM. They are actually brighter than some cheap ones which claim to have 10000LM or 12000LM.-- Beam Pattern. Halogen bulbs are known to retain beam pattern the best. But the 9003 I bought shows a perfect shape. I can see the contour reflected on the garage door like super clear. -- Heat dissipation. Comparing to other LEDs, this one is particularly good. I have tried LED lights without fans, gosh, THEY ARE HOT, making the durability much shorter. Yosaky 9003 comes with a fan, which keeps the working temperature pretty low and pretty quiet as well. I am expecting 5+ years of use on this pair. Will update this review if anything changes. -- I did some research on FC Chip, COB and CSP. Not claiming an expert myself, but COB ones are the worst in terms of durability, beam pattern and brightness. FC Chip are similar to CSP in brightness and beam pattern, but they are cooler when working. So FC Chip has an advantage there. -- External Powering. I am glad to see Yosaky comes with external powering at this price tag. LED headlights with external powering last longer than the ones without. Cons -- The Package. The package is way to plain and lack of design. It’s very unimpressive at the first look. -- Cable Length. The cables are not as long as I wanted them to be, but they are long enough. I have seen people complaining about long cables making troubles with dust cap. But my dust cap has room, I like cables longer, which makes installation easier. All in all, I am pretty happy with this product. A solid 5 star! Will purchase again.

Quality product, easy to install, definitely recommend!
**Updated 11/12/2018** I have had this LED installed for a while. It’s been working great and I really love it!This is the second time I purchased a Yosaky product. Last time it was 2014 when I bought a new Toyota Corolla. The car came with the halogen lamp which was kinda OK, at least my husband thought so. But I really can’t see that well at night. A friend of mine who runs an auto repair shop recommended the Yosaky LED headlight bulb. It was the S Series back then. It was $90 something without installation. It was great, and the light was still working when I sold the car last month.I got a Toyota Camry last month and wanted to do the LED upgrade, except this time my friend moved out of California. But I was feeling courageous to do it myself (I saw the guy did it once anyway).First, I took down the halogen light and made sure it was H11 there, and then went shopping for the LED replacement on Amazon.Then I found Yosaky, but not the S Series. I have no idea what’s different between the S and the K Series. I just assumed K Series is newer and went with it, cause I like Yosaky so far.I waited 3 days for the Amazon 2 day shipping (well, I ordered in the morning) and got the light. It was nicely packaged and feels heavy. I just removed the dust cover, unplugged the original halogen, then inserted the new LED. I turned and fastened it, put the cover back. Took me less than 10 minutes. I know some cars need some tweaks on the dust cap or something, luck for me, my car doesn’t.I tried it at night and it was sure bright (especially with the fire and smoke going on in California).Anyway, I am really happy with this new K Series and would definitely buy it again if I ever get a new Toyota. Quality product and easy installation. Don’t get the pro installation, it’s a rip off for such small task, you can do it yourself.

Great ligth output
I got them yesterday and installed them rigth away. You can see the difference in ligth output. I will probably get a second set for my Honda CRV seen in the video for comparison.

very solid product with good quality
It’s been a month since I installed the bulbs. I left it on for 10 minutes and it was still just warm to the touch – not too hot – the fan is pretty solid to carry the heat out.What do you think of the images? You think I am showcasing the bulbs? Nah, I am showcasing my driving skills. That was a pretty steep and twisted road, and I still managed to take a photo that crisp while steering the wheel with one hand.It actually only took me 42 seconds to replace the bulbs! I wanted to shoot a video to prove it, but both of my hands were busy doing to work – I wish I had a third hand which would really come in handy.You think I am mechanic? Nah, sorry to disappoint you, but I am an accountant. I guess I can beat other accounts in mechanics and beat other mechanics with my driving skills.I would give it 10 stars – 5 stars for the product, and 5 stars for me of course. But Amazon only allows 5, so I reluctantly gave them all to the product.Enough of me babbling, these are great replacement bulbs, you can’t go wrong with them.
