Review on 🚐 Facon 4-1/2'' LED RV Puck Light: Super Slim & Bright Under Cabinet Light, 2-Pack Surface Mount Ceiling Dome Light for RVs, Trailers, Motorhomes - 12V DC Interior Lighting with Push Switch, 3400K Warm White Glow by Joseph Winfrey

Aside from ease of installation, there's no reason to buy these cheap lights. After a short time, they will begin to fade and/or flicker. There doesn't seem to be a way to stop them from flickering once they've started. Jayco RV came with them and when one of them failed (flickered) I got them because they matched and were the same brand. There are many better RV attachments out there and I would recommend purchasing one through Facon. Haven't found a way to return without spending more than they're worth.
