SEALIGHT H10/9145/9140 LED Fog Light Bulbs, 6000K Xenon White, 27 SMD Chips, 360-degree Illumination, Non-polarity, Pack of 2

I’d say these fall somewhere between “great” and “pretty good.” The brightness is respectable — not the most powerful set I’ve tried, but definitely a step up from stock bulbs. What impressed me most was how straightforward the install was. The slim design slipped right into my fog light housings with zero hassle. The light output has a clean, white tone that makes the car look more modern and improves visibility. That said, if you’re chasing maximum brightness or top-tier performance, you’ll probably want to spend a bit more for a premium brand. For everyday driving, though, these are hard to beat at this price point. Easy to install, solid quality, and a noticeable upgrade over OEM.

I ordered a set of d3s light bulbs a few months ago,nor very long ago..I took a 12 hr drive back home,those replacement supposedly 600k d3s light bulbs where not bright engough.so I ordered those and wow,what a big difference. I don't know how long they will last,easy install, very bright,nicely packed...highly recommended.

I would not recommend using these as replacement for your H11 headlights!!!!! These are specifically made to be fog lights. they make headlights as well but the headlights are more expensive. I see a lot of reviews of people complaining that they are not bright enough for headlight use that’s because they are not headlights. They are amazing fog lights and they are bright AF. I was considering upgrading my headlights to SEALIGHT LEDs, but since I wasn’t familiar with the brand—and the DS2 HID to LED upgrade runs about $80—I decided to test the brand out first with my fog lights, which were on sale for just $15. Before making the 80 dollar investment. Let me just say: THESE ARE THE HIGHEST QUALITY BULBS I HAVE EVER LAID EYES ON AND INSTALLED IN MY LIFE!!! The build and performance shocked me, especially at that price point. Honestly, they put Sylvania to shame. I wish I had made the switch sooner. Not only were they cheaper than the standard bulbs I used to buy, but the quality feels 10x better at less than a quarter of the cost. Even at the regular price of $25, they’re absolutely worth it. In my opinion, these bulbs are so well-made I’m surprised they don’t cost as much as full headlight replacements. I’ll definitely be purchasing the headlights soon and will update this review with photos and videos. As for the negative reviews you might see—take them with a grain of salt. Some people simply won’t be satisfied no matter what. My only complaint has nothing to do with SEALIGHT but with Amazon’s delivery service. The driver literally threw the package against the mailroom wall (several people caught it on video). I’m amazed the bulbs survived that. One last tip: check whether your vehicle requires an anti-flicker ballast. If it does, SEALIGHT will provide one for free separately you just have to let them know you need one. Mine didn’t need it, but I thought that was a really thoughtful touch from the company.

I always use bulbs that are designed for their specific purpose — whether it’s halogen, HID xenon, or dedicated fog-light bulbs — because beam pattern, cutoff, and distance rely on the light source sitting exactly where the engineers intended. But for only $16, I wanted to see if these LEDs could come close to, or even match, a good high-output halogen in real driving conditions. And honestly, for this price, the performance is impressive enough that the product deserves five stars on value alone. 🔧 Installation & First Look Easy install, clean white color, noticeably brighter on a wall or fence. If you judge only by close-up brightness, these LEDs look excellent. 🔍 Real Road Performance (Where It Actually Matters) I tested them properly — same camera settings, same distance, before/after photos — and that’s where the difference becomes clear: ➡️ Up close: LEDs look bright. ➡️ At distance: good halogens clearly win. Here’s what you can see in my photos: With halogen, the beam has a defined cutoff line — the tree in the distance shows exactly where the light ends, and my neighbor’s garage is more visible. With LED, the light scatters upward — the nearby tree becomes washed out with no sharp edge, and the distant area is actually less illuminated. Brighter does not mean better. The LED beam is wider and whiter, but less controlled and less informative in real driving. With halogens, I could see deeper into corners — pedestrians, objects, road edges. With these LEDs, the light is: Bright? Yes. Precise and helpful? No. 🟡 Final Conclusion Great color, modern look, and an extremely attractive price — but brightness ≠ visibility. In real-world driving, a good high-output halogen still outperforms these LEDs, especially for distance and cornering. I’ll be switching back to upgraded halogens.

These lights worked perfectly to use on a 2015 Audi A4 Premium. They look very good from the material they are made out of and offer heat resistance with a build-in fan. These are exactly plug and play as the D3S plug fits directly into the extension wire when replacing headlights. I had Philips Xenons before this and replaced it with the Sealights as I used this brand before on another car, and the light quality is good with an excellent brightness increase compared to the Xenon lights. They don't create any extra noise and I have not had any failures thus far. These truly were the most plug-and-play option that I found with a LED light in it.

My wife loves these. They are bright and a good replacement from the halogen lights.

Easy to install on my daughter’s 2014 challenger. Very bright and bright white, clean color. Great price with great value.

all good

Quick and easy to install. What difference in light colour and brightness compared to the original bulbs. Would recommend these due to easy of replacement and quality at this pointl

La luz es de buena intensidad, para unos neblineros de jeep, es mas que suficiente... el problema que tuve fue que los bulbos no quedan alineados correctamente (90°), no tienen ajuste, por ende, no proyectan bien... ademas de que tuve que modificar un poco la ceja del seguro del conector, ya que viene mas larga que la del foco original... con que tuviera ajuste, sería perfecto...

Purchased these to replace oem bulbs. Wish I had sooner, easy install on my Jeep JK , no codes on dash. Plug and play. Extremely bright! Slight flickering but barely noticeable really. Will purchase again if needed and definitely recommend to family and friends.
