AKKON Replacement Halogen Projector Headlights for Cadillac CTS & CTS-V - Left & Right Driver Passenger Side Lamps (Black) - OE Fit, Enhanced Night Driving Safety

Fits great, works great!They started to yellow within 18 months and now need to be replaced. I polished them at 24 months and it really didn't do muchEdit: Left review of my first set from them in place and have added second, ongoing review below it. Rating dropped to One Star due to shoddy product and less than helpful customer assistance.2013 Cadillac CTS SedanThey Looked and worked great... until about 3 days after the 90 day warranty period expired.Then, the Passenger side blinker bulb just stopped working.Worked with my garage (installation/removal process on these things is a beast; garage charges about $200), and pulled the assembly, pulled the bulb... and nothing wrong with it. Tested and it lit up no problem. Tested the "pigtail" that connects the electrical system to the assembly... also fine.Garage team says it's either A) a bad control circuit board inside the assembly (most likely/95% the answer), or B) a wiring failure inside the assembly.Either way, they can't fix it.So now, I'm out the garage costs, AND need to replace the whole passenger side assembly.Would love to hear if the seller is willing to offer a solution.Edit: Luckily I had bought the insurance through Amazon for some reason... so, after a less than easy process I was sent a refund for exactly the cost of the headlights... no help on the install costs.Decided to tempt fate and got them again. Almost Same result; Worked great at first, then the passenger side turn signal stopped working about 2 months after.Seller's 90-day warranty is actually 60 day refund or 90 day replacement they tell me, so Now I'm starting the process of figuring out how to get that done.... I'm less than hopeful as their first email was the refund denial and the request for "a photo of the problem"... Waiting for their reply as to how I get a photo of the blinker not working.More to follow as I detail the tribulations I go through trying to get this made right.I used this item on my 2011 CTS sedan. A couple of months after having them installed they started turning yellow. I thought they would’ve lasted at least a year.The product look really good but the only issue I had was the headlight fogs up so I used my old bulb cover place seals and one bulb blow within a week I replaced the bulb and have not had any problem since. Over all I would definitely purchase this product. Fits and look perfect on my vehicle.. ThanksGood so far. Unfortunately these headlights use an H1 bulb instead of the factory H11. They work fine, but H1 bulbs are much harder to install vs 90xx series or H11's. Materials appear to be very similar to factory. I replaced high beams and low beams with LED's in order to keep temps low inside of the housings and so far I haven't had any fogging issues since installing them this january. I'll update my review after several months, but so far so good.They fit fine after a bit of modification to the car. The bulbs they came with were likely intended to be put on cars for sale. After I upgraded the bulbs and adjusted the aim they really are just like new.God awful. These seem to be a very economical option to the more costly OEM product and after install seem like a great value. However, they are not. After having them installed for 4 months, the passenger side headlight went out. I was hoping that it was just the cheap bulb that came with the lights that went bad. But, after removing my bumper cover and changing the bulb, the light still did not work. After checking my connections with a multimeter, it was determined that there was a short in the unit itself. So, I proceeded to try to get a replacement headlight assembly, but to my surprise, what I got instead, was a very short email from the seller basically stating, too bad, these only have a 90 day warranty your out of luck. No options or offers.Lesson learned.My advice is obviously not to buy these and spend the money to buy the OEM or something that provides a better warranty. There is a reason they only offer a 90 day warranty, and that reason is because they know that their product probably shouldn’t be allowed on vehicles. I’m curious to see if they’ve passed mandatory auto safety inspections.
