HoldCY LED Headlight Bulbs - H7 60-watt - 12,000 lumen - 6,000k Cool White - Halogen Replacement Bulbs - 1 Year Warranty (1 Pair)

I bought these H7 LED headlights and the adapters for use in my MB E350 coupe. The install with the adapters was easy and took less then 30 minutes. i turned on the headlights and they worked! So I was very happy. I didn't drive at night for a week but when I finally did my joy came to an end! After about 10 minutes the passenger side headlight began to flicker and then finally dimmed to about 10% brightness and never recovered.Thankfully, Amazon has a great return service and I dropped them off at Kohl's for a refund to my credit card.
