Passenger side would not turn on dim until a decoder was installed , also the bulb would not line up in the 9:3 position , money was returned I used them. For a little while , until the drivers side quit workingThey were impossible to set because of the position of the diode

L'ampoule DEL était trop grosse à cause un capuchon à l'intérieur du globe de phare avant, j'ai dut le couper pour que le DEL entre . Je ne pense pas que ça de l'impact sur utilisation, je crois que le capuchon était pour éviter la surchauffe de la vitre par les phares standard , le DEL chauffe moins. Voir photo

I had these bulbs installed on my 2008 F250 and they're really good - super bright. No issues with the install, basically plug and play. It sure makes a difference with bright headlights when traveling on the highway (safety in terms of being seen) and on darker poorly lit roads. Highly recommend, you won't be disappointed.

Fast simple to the point review:1) bulb doesnt fit in the headlight assembly. It doesnt lock into place. The 3 prongs are somehow different then the original halogen bulb.2) bulb connector doesnt fully engage on the car headlight pigtail connector. « No click »3) bulb leds orientation is completely offset compared to the original halogen bulb filaments = poor light beam alignment.Any poor fitment of a bulb will results in water condensation in the headlight assembly in no time. There is no point to try to remove some plastic with a sharp knife or a dremel. Headlight assemblies are very expensive.Sent back to Amazon. No thank you!*UPDATE*The seller contacted me and offered me to send me a new set of bulbs. They offered sincere apologies for the bad results with the first set of bulbs. It was probably a set that escaped their rigorous QC. The new set that they sent me works perfectly. The connector on the bulb connects positively « clicks » on the car connector. The bulbs LOCKS now perfectly in the headlight housing without any play. The light output is powerful and could be adjusted easily to avoid blinding incoming traffic. I won’t have any hesitations to purchase more products from this seller in the future. Their customer service is simply a 6 STARS!

I have used several different led plus high output or halogen headlight bulbs in the past. These balls have poor coverage, and the low beams are brighter than the high beams. i can not get them adjusted properly. i am very disappointed!

First off got these to replace my stock halogen lights on my 2012 ram 1500 and they plug in to the old sockets no problem and work well. I can see quite well at night now. But it did take me a minute to get them in the right way as the tabs that lock into the assembly holes fit in any way. I could line it up with any of the assembly slots and it would twist and lock but the light would be dull until I got the right angle for the LEDs to reflect off the lens. The old halogen ones go in only one way and twist and lock.I do have a little bit of flickering and there is a delay in the switching from high to low. Drivers side goes to high when I flip the switch and passenger side goes high a second or so later and vice versa when switching to low, passenger goes low first then drivers the second or so later. They also don’t appear to turn off with the turn signal or when the DRL sensor is in light. They do state that they work in 99% of vehicles error free but an additional decoder might be necessary so I’m guessing my truck falls into that 1 percentile, if only my income did lol, I will be trying a decoder to see if that will help make them work 100% like stock. Overall happy with them.Update 3-23-23 I have installed a set of decoders and the lights work with no flickering, no delay in switching from high to low and the drls now work as intended as well.

The first thing that needs to be said about Fahren Auto (the seller), you will never find a better customer experience ever! This is going to be a long review but it will cover both the product and the seller. Its almost scary transitioning from stock lightbulbs to LED with all the comments and "issues" associated with doing so. Well, with this seller, you can put those fears to rest.Fahren Auto (seller): Im starting off with the seller cause the customer service I received left a way better impression then any product ever could have. My story. I have a 2010 Dodge Ram 1500 I bought from a buddy. The truck had new headlight assemblies and halogen bulbs. The light output was terrible. So I did a couple of weeks of research. Youtube for best leg bulbs / many hours of reading specs and reviews / searching amazon for the brightness (600%), color (6500k white) and canbus / chip (internal) I wanted without cresting the $100 mark. With those specs in mind, I chose these bulbs.My first attempt to install these in my truck left me questioning if I had made the right choice. Other then color, they didnt look much different then the stock bulbs. So the next day I did another attempt and although I had a better outcome, the lights were just not right. Thats when I realized the passenger side bulb wasnt sitting right. It was clocked at 2 and 8. While the drivers side, which was way better, was clocked at 12 and 6. I contacted the seller through the asked the seller a question within amazons page. It was a Friday evening with a holiday on Monday. So didnt expect to hear back from the seller till at least Tuesday. I was contacted Monday first thing. I was offered a replacement but if I could go ahead and troubleshoot the bulbs from side to side. That seemed more then fair, so I did so. Thats when I learned the passenger headlight assembly was manufactured incorrectly. It was impossible for the bulb to seat at the right clock. So it wasnt the bulbs fault at all. It was also during the testing that I realized the high beam on the driver side bulb wasnt working. So did testing on that bulb as well. Because the customer service was so timely and nice, I tested everything. Wiring included. Just to make sure it wasnt a voltage or other issue. In conclusion, the original issue turn out to be a fault on my side with the messed up headlight assembly. The other bulbs bright was indeed not working. I let the seller know how the trouble shooting turned out and offered to pay for a replacement set that had the adjustable clocking feature. Sadly, they did not have a bulb with that feature and all the other specs I wanted. So they let me keep the original led bulbs and refunded my money so that I could buy the bulbs I need. This goes beyond good customer service. Not being a get something for free kinda person, I instantly ordered new bulbs for my moms car from this seller. Got another buddy currently looking at bulbs for his car and figuring out which ones he wants. Also from this company. You dont get customer service like this very often. And when you do, its your responsibility to ensure, that company sticks around and is rewarded for their effort. Thus why I will only buy bulbs from Fahren Auto. And anytime bulbs come up in a conversation, I will praise their service. And their product.Product: I chose this manufacture because their products all have 4+ star reviews. They are mentioned as top of the line for their mid level bulbs and pricing. I wanted a bulb that had the kinks worked out and was very effective. This was the bulb that kept coming up top on my list. I didnt want to blind anyone or draw someones attention off the road with an odd color. And although it took a bit to get my issues (mentioned above) worked out, I knew from the first test, these bulbs were going to be perfect. At 600% brightness and the cut off, I can get the most out of the light without pissing off oncoming drivers. The color is perfect. No blue tint at all. These are the exact bulbs I was wanting. My experience is kinda a worse case in terms of installation (completely due to the issue on my end). But here I am praising the bulbs I received and the customer service of the seller. Just imagine how grateful you will be with a straight forward installation.
