FAHREN H11/H9/H8 9005/HB3 LED Fog Light Bulbs Combo, 40000 Lumens Bright LED, 6500K Cool White IP68 Waterproof,Pack of 4

****UPDATE 2**** I have installed them and sure enough the set screw caused my suspected issues on the H11, and a unexpected set screw issues on both 9005 & H11. The unexpected problem, was the set screw will not hold the collar as intended. As you should know, the proper installation require the LEDs to point to 9 & 3 o'clock so you're lights don't blind people and work as intended. The set screw and the collar is how you adjust this. When I was installing both sets, the force needed to push down the seals, was so great that once you turned the bulb to lock it in, the set screw slips and then your bulb is no longer where it should be. The fix I used was to use a cotton swab with a very thin layer of lube on the seals and mating surfaces, to lower the pressure needed to turn and lock bulb into socket. Also, I realigned the setscrew where it should be and tightened it up. Even with the fixes, I had to do it twice for each bulb. Also the reason I did it twice was part of my original complaint, the H11 set screw grabbed the seal and twisted it. The second try with the lube and it was ok. The low beams work incredibly well! Since I aimed them properly, they are not blinding yet I can see everything. The brights are unbelievably bright, but hard to aim.________________________________________________________________ The 9005 pair appear to be ok, but I have not installed them yet.The H11 pair have a definite factory/engineer defect. I have not installed these yet, so an update will be coming. As most of you know, modern headlights need sealed to prevent moisture and dirt from clouding up the lens. So this factory defect may not seem to be a big deal to some, but it could allow moisture in around the seal/O-ring. Picture 1 shows the blue O-ring isn't straight/flat. It has a bump. At first I thought it was just out of the groove, but on further inspection the allen set screw used to align your LEDs at 9-3 o'clock is what's holding it up. I then thought maybe it's not screwed down all the way, but I used the supplied allen wrench to check tightness. They were already tight Picture 2 & 3 I pulled the O-ring up to fully expose the set screw. Picture 4 & 5 I took notice of the position of the seal, so I would place it back properly and only fixed one bulb at a time to be sure. I used fingernail clippers to cut a small notch to make room for the set screw. This was my choice to fix it, but you could always try to find a shorter set screw, or grind this one down if you're good at working on tiny parts. Of course you could always return them Picture 6 & 7 is where I reinstalled the O-ring. Notice I used a pen to mark the O-ring with a small line so it was easier to line up the notch I cut to the set screw. Be sure to get the O-ring set straight in the groove. Also I am worried the O-ring could slip when I install on my SUV, so I gently cleaned the O-ring and the groove with alcohol. I used a cotton swab on the groove, carefully so as not to get any alcohol on the bulb or circuits. I also plan to put just a tiny bit of dielectric grease on the contact surfaces when I install them, to help keep the seal I place while turning them . Picture 8 is of the positive and negative marks ( + - ) on the plug. For those that don't know, LED is a Diode, a Diode that is Light Emitting, hence the name LED. A Diode is used to only allow electricity to flow in one direction. If you see a plain one on a circuit board, it has an arrow on it showing the direction. Some LEDs you don't have to worry about which side is positive or negative, they may have circuitry that makes it work either way. Some LEDs must be wired/plugged in to the correct polarity. I'm not sure how these are, but the plug is marked to help you. If they don't work, just flip the plug around. If you have a multimeter, you can use it on the car side of the plug to figure out for sure which side is positive. I'm confident I chose good LEDs and my fix will work. I probably have ruined my warranty doing this, but it is what it is. Sorry for the long review. I am off work for now and it's too cold to go outside so I am bored. I'm hoping Fahren sees this and replies and/or fixes the issue. It seems to be difficult to navigate their website to look up product or contact information. When the weather gets warmer I will install these and update my review

These LED headlights are good but not the best. They have no distance, but are bright as hell. But they flicker, A LOT! Sometimes you can hear the little fans doing their best to cool this heaters down. Will I purchase again. Yes, if they where on sale at a significate reduction in price. My stock Prius LEDs where better.

I upgraded my poorly lit stock 2012 Mazda CX-9 headlights to these and man what a difference. I’ve had these installed for about a week now and I can’t say enough good things about them. They really light up the nighttime road in front of you, and on the sides of the road. I was a little worried people might think I have my highbeams on, but nobody has flashed me so far. I know I would highly recommend these bulbs, well worth the money.

A couple weeks ago I installed these in my 2020 Ram Bighorn. Because I have huge hands and the design of the vehicle, it took a lot longer to install the lights than I expected, having to remove engine bay components and accessories. It was dark once I had them in place, so I fired up the truck and hit the switch. BOOM! It was like I was shooting sunbeams from the front of my vehicle. I had my wife come look and she was like, "People are just going to LOVE you on the road." Happy with my purchase, I took my swollen and beat up hands to bed. The next morning I got up, excited for my early morning drive with my own personal sunray. Fired up the truck and the H11s blinked alternately, about once per second, five times and then went dark. They stayed dark. I restarted the truck and turned the lights on- same thing. I then flipped on the brights and they too flashed in the same pattern and then went dark. "Guess I'm not going to work today." With my aching hands I pulled the bulbs and reversed the wiring clips as suggested- nope. I left the dust covers off- nope. I pulled the lamps and tried them in my wife's vehicle (which already has another brand of aftermarket LED upgrades) and they flashed the same in her vehicle too. I contacted support. Over 24 hours later I was told I would need to install an additional "decoder" to make them work. Buy this point my hands hurt so bad and I was so frustrated to not be able to drive my truck that I noped out of that idea, pulled the bulbs for the 5th time and put the crappy halogens back in and then sulked while icing my poor hands. A few days later I picked up some H11's of the same brand I put in my wife's car and they worked perfectly. They have for over a week- not one single problem. So I thought I'd give the Fehrens one more try... maybe I did something wrong. My truck looked like a beacon on a channel buoy- blink, blink, blink, blink. I reinstalled the other LEDs and will be returning the Fehrens today.

Low bem flickering than go s dark

They're extremely bright. However just recently after 5 months my passenger lowbeam has turned a blue hue it's weird having half white half bluish purple

This is the 2nd set of lights from this company. I was very happy with the installation and results of the DIY LED light upgrade in my 2014 Prius V. Zero modifications needed there.Pictures are before and after modifications I felt I needed to do to the dust covers of my 2014 Ram 2500 Hemi 6.4. Although what you see zip tied to the outside of my dust cover would have fit inside with the actual bulb housing, I couldn't really find the best place to secure them and keep them away from heat other than what you seen.Yes, I secured the modifications/cuts & holes so that dust and/or moisture would have a difficult time getting in.All in all, it was fun and not too hard. Really love the lights and all it exposes late a night, whether they're street lights or not.

I have a silverado 2500hd 2020I received the package at least 2 weeks late. Very bad customer service.2 bulbs out of 4 don't fit even though it said it does on Amazon and the 2 bulbs who fit flicker and go off after 2 seconds.Do yourself a favor and walk away...
