Review on Powerful 5 Pack Leisure LED RV LED Ceiling Double Dome Light Fixture for Car/RV/Trailer/Camper/Boat with ON/OFF Switch Interior Lighting - DC 12V Natural White 4000-4500K, 48X2835SMD by Tim Bunker

I have replaced the stock bulbs in my 2012 Puma trailer with these and am very pleased. Ease of installation. MUCH brighter than the lights they replaced and a cleaner white light that is comfortable for middle aged eyes. They do have tan lines as others have reported but they are not noticeable or bothersome (I looked for them based on other reviews). In my opinion, previous standard incandescent bulbs didn't cast lines because they were too dim for that - lens lines are only visible when bright. I'm happy.
