Like so much crap sold on the internet these days, these are made in China with very little or no warranty.
The first ones listed by the OP from eBay have a 30 day money back guarantee and then a very short 60 day warranty period. They are shipped from Arcadia, California but originate from Hong Kong (as indicated in their eBay store but not on the ad) but God knows where they are manufactured. And both the guarantee and warranty require you to pay shipping back to the seller and the only refund you will receive is the amount of the goods...not the shipping both ways even if their product was defective. So you'd be buying Chinese made crap with a very short money back guarantee period and a 60 day warranty. Seems like the buyer is assuming all this risk for something that may or may not work out especially if they fail (condensation inside the lens, bad LEDs, poor construction, etc.) in six months or a year.
As for the second set posted from Amazon and sold as VLAND from Yuanzheng, these are made from a company located at Room B, 10th Floor, Li Mei Building, 788-790 Nathan Road, Mong Kok, Hong Kong. They have a 30 day return policy and then you're stuck as they have zero warranty on them. VLAND actually sells these on their own website where you can see their return policy at

Bottom line - We all spent at least $35,000 to $60,000 on a new Ram with a warranty. Purchasing cheap *** made in China junk with damned little or no warranty for something as critical as headlights is penny wise and pound foolish. Yes, many of us have purchased LASFIT LEDs (or other brands) to replace our halogen bulbs with LED and most are made in China but the cost is a fraction of the price of these headlight assemblies. However, LASFIT has at least a one year warranty and two years on many products but these headlight assemblies from China have virtually no warranty. Personally, I would keep looking...
