I used 2011_LED on Ebay with great results a few years ago. I got soft-white LED panels. They had a base that plugged into my overhead light and some double-stick tape to hold the panels up against the light reflector. It has been at least 3 years now and all panels are working fine. The drop in current used from the battery is amazing. Now we don't make any attempt to conserve lighting when boondocking! I also got a LED replacement for the porchlight. This bulb (which was expensive, $8 or so) is much brighter than the old incandescent bulb that came from the factory. The old bulb got so hot that the plastic lens over the light started to melt. With the LED, almost no heat thus no more melting.
Good luck to you....let us know what you finally decide!!!
