Word of caution from my own experience... Make certain whatever LEDs you do buy, they are rated for more than just 12v, specifically up to 14.5v. I bought a bunch of LED lights off of Amazon that seemed just fine, plugged them into my camper and thought I was good to go. I seldom use shore power but the one time I was I had the lights on for about 30 minutes and started to smell burning electronics smell. After a few minutes I narrowed it down to the LED lights and took off the housing and attempted to unscrew the bulb only to have it all fall apart on me! The bulb had heated up so much that it made the solder very weak and my touching it caused it all to fall apart.
I still use the same bulbs but only because I'm never on shore power and I've already spent the money so I might as well get my use out of them. The few times I am on shore power I keep a close I the bulbs and make sure not to run them for too long.
