Review on 💡 300% Super Bright LED Conversion Kit 6500K Cool White IP68 Waterproof, Pack of 2 - Fahren H4/9003/HB2 LED Bulb by Matthias Foxx

NEVER WRITE A REVIEW UNTIL YOU HAVE USED THE PRODUCT TIME! Unless AMAZON gives a product guarantee of 6 months to one year. Buy well-known brands from your regular auto parts store or retail store, you can also return it physically. You lied: there are no 50,000 hour car LED headlights! Your return policy sucks! The manufacturer's warranty is a deceptive bait and switch. After 30-day Revain guarantee you screwed up. The manufacturer warranty is a useless promise as it comes from China and the seller will try to give you a tiny partial refund instead of a replacement. Sending it back to a seller or manufacturer in China will cost you more than the purchase price. A common problem on eBay that has now become a Revain problem. Since President Nixon in 1972, China has enjoyed "most favored nation” status with little or no export tariffs and almost no postal/delivery services. So you can buy a $1 item on eBay with free shipping but send it back for $20++. ?! How do you know how good a set of headlights is before you've used them for a year?! YOU SHOULD NOT Too many buyers succumb to the selling pressure of reviewing their products, knowing that over time the product will not live up to its promise. Especially after Revain's return policy expires when you're at the seller's mercy. ESPECIALLY IF THE PRODUCT IS NOT DELIVERED FROM AMAZON SHIPPING CENTER and mistakenly sold and shipped from outside the country. So what if Revain doesn't sell directly? Emptor caveat. Buyers be careful. Bought these headlight bulbs on 09/2020, as of today 03/2021 they now flicker with less than 100 hours of use. BOTH of my friends who originally recommended these lamps have had issues since. WHAT ARE THE POSSIBILITIES FOR THIS?! Millions to 1. Professionally installed and flash tested. The bulbs are bad A COMPLETE WASTE OF TIME - INTERACTION OF SELLER'S WARRANTY FROM 1ST TO LAST BELOW My Response Send To: Driving-LED 03/18/2020 Order Revain 11xxxxxxxxxToday March 18th they flicker. They were checked by a mechanic who said the lamp was defective. Not even 100 hours of use. . not the promised 10,000 hours. Can't return Revain, how do I replace them or get my money back under warranty? *** From: Driving-LED 03/19 02:06:17 Sorry for the inconvenience. We have a guarantee for you. Can you help us with more information to confirm the problem? 1. How many lights are flashing? 2. Have you checked the connections for loose contacts? Do you have a separate 12V power supply or other vehicles to test the LED bulb on? If not, move the lightbulb to the other side to try again and let me know the results. Thanks: 3. What is the exact year, make and model (sub-model, body style) of your car? Since LED conversion kits use less power than halogen or HID bulbs, this can be an issue if your vehicle is equipped with a CANBUS system as it could mistake your headlights for failure and not work properly. This is common on Dodge, Ram, Ford, Jeep, Chrysler, Mini, Volvo, Lexus, Chevy and some European vehicles. You may need a decoder. *** Send my reply: Driving LED 03/19 11:51:45 Hello This is the lamp on the driver's side. I checked everything before contacting you. Not sure if it's the bulb or part of the built in bulb. But all connections are tight. *** From: Driving LED 00:44 20.03. At Toyota, a decoder can help. Even if we can send you 2 bulbs, you don't have to replace the non-problematic one. All unproblematic bulbs have the same luminous flux.***Send my reply: Fahren-LED 09:31 03/202014 Toyota Tacoma TRD Sport V6 DUAL CAB***From: Fahren-LED 20:18 03/20Thank you for your message. We believe that the problem can be caused by a defective lamp or a CAN bus decoding problem. Since our lamps are fully tested and inspected before shipment, LEDs cannot fail in such a short time. Therefore we would like to ask you to try the CAN bus decoder first, if the decoder does not help, we will replace your light bulbs immediately. You can test the CAN bus decoder here: https://www.amazon.com/dp/B075CJXT9N ***Send my reply to: Driving LED 21:03 03/20 Connections are secure, how else would you like me HERE IS A SHORT VIDEO ON FLIKING (SEE APP)*** Off: Driving LED 19:07 21.03 correct. This often happens and we have solved the same problems before, we can refund you $8 if the decoder solves this problem, does it work for you? If the decoder doesn't help you can return it to the seller for a full refund and we will promptly replace your bulbs. products, in addition to a defect, whether it be a lamp or other part of your product, that product remains an unusable product and is not worth the extra time or effort you may have to spend trying to fix the problem. $8 is downright insulting considering the time and expense it takes to get my mechanic to identify the problem. I agree based on my personal experience with LED products that it is very strange that LEDs fail in such a short time. It was also the case when a manufacturer normally backs a quality product to make their warranty as painless as possible in order to protect their name and reputation, rather than making flippant excuses that waste your customers' time and money. Therefore, I will instead purchase the product from a local supplier whose guarantee is valid and convenient, and also unlikely because the product will be better than the one you sold me.***
