SiriusLED 4th Gen Extremely Bright 7200 Lumens CREE LED Bulbs for Headlights Fog Lights DRL Conversion Kit With Color Change Option H4 9003 HB2 Dual Hi Low Beams 6000K Xenon White

Great shipping love the lumens output so easy install play n play, minor fan noise but does not bother me. The high beams are very bright and light every sign that it can reflect

Great amount of light but not quite right for headlights. These LED bulbs look and feel solid. Had a great experience with SiriusLED customer support. My first set of H11 started to flicker after about 9 months, slightly disappointing for bulbs you expect to last a very long time. Contacted SiriusLED and explained my problem. Within just a couple of emails, a replacement set was sent to me no charge. The 4S gen was sent replacing my original 4th gen. The 4S construction is slightly different with a cover for the LED element. Unfortunately this bulb design is still not ideal for replacing a standard halogen filament. The material used for the screw connector from bulb to driver is also too thin and easily overtightened, braking. I used electrical tape to secure and seal. Personally I would not buy again, at least this generation; newer ones look much better. I would not recommend for anyone with Projector headlights because of the bulb design; appears better in newer generations. Possibly much better in standard headlight assemblies.

I hate to say the cliche "If I could leave one star I would" review but in this case it's very true. I've tried several sets off this brands lights on my car and they always fail. I keep trying them because when they do work they look the best in the car and work the best. This final set failed exactly 22 days after the warranty expired. I will no longer be trying anything made by this company and I hope that you don't either.

After relatively simple install I was excited to drive around with new LEDs, the small fan noise did not bother me at all.The light on both brights and mids was ok, definitely not worth the price I paid for them. I have seen regular light bulb produce more defined straight forward light, I also seen the same regular bulb burn my reflector, where this LED takes better care of the heat by dispersing it with the fan. It looks like when I turn the brights on, it just lights up another section of the LED. That makes it look like there is more light, but in reality you don't see that much further down the road.I have a pretty low to the ground car, couple times after forgetting to switch to mids I realized that no incoming cars blinked at me for driving with brights on. The bulb is pretty good at illuminating the signs on the side of the road, as the light color works very well with their reflective surface.After only about 3 month or so one of the lights started flickering and getting darker, another month gone by and the 2nd bulb followed suit. Eventually both bulbs would shut off forcing me to drive with Brights on.At this point, based on my personal experience, I don't think they are ready for the market !

FREICKIN AWESOME! I had HID's in my hummer. They were great. but subject to "bumps" in the road.All of the LED bulbs i had found until now were like 400 bucks each. I found these and the price was excellent with the incredible upside potential of lasting longer than the car they will be mounted on, and also containing high/low beam in single unit and fan for cooling down the driver. They also provided the same temperature as the HID bulbs while running lower voltage and draw on the system. Straight plug and play as well, so there's no need to add weird wiring s***.

While the bulbs are bright, after 2 months of mild usage, 1 has already stopped working. I would love to contact the seller to "make this right" but it isn't obvious how I am supposed to do that. If you are the seller, please reach out to me to replace the issue or the negative review stands. I can't believe that for $100+ the quality of these lights is such that they fail. Nice. Please contact me to make this right.

When lights came in, I read and re read instructions. Was about to return then... Was not sure if they were going to fit if I had dust cover like it said I did. Started to take apart my 2014 f150 to find out there is no dust cover like instructions showed. So I put in and start to finish install took 20 min. Start to finish. Lights are very bright. I ordered 6000k but box says 3200 on cover. They are not white white but very bright almost a light blue tint to them. Way better then past HID. Even though I have HID yellow as my fog. We will see how they hold up...

They were packaged nice, easy to install, and they were just as bright as my HID's when I installed them. I was so happy because I was fed up with replacing ballasts and such with the HID kits, but after about 6 months of having them in my 2008 Pontiac G8, they started flickering...Ugh I'm so frustrated with all of this, I've spent way too much on different headlights than anybody should ever have to, and after all that money spent, now I'm back to running stock H11 bulbs so I can see and don't have to deal with flickering. Don't buy these LED's, hopefully soon someone will come up with a good setup that's bright and won't give you trouble...
