Welcome.
Your best bet is to buy some inexpensive LED's off Ebay or Amazon in different color ratings and different lumens levels, a few singles. See which you like the most and then order all the replacements you need.
Everyone's eyes and lighting perception is different so any recommendation may not fit your needs.
FWIW, I used all flat panel LED's and bought them from an Asian vendor through E Bay. I haven't had any failures and the price was low. Don't get hooked into buying any expensive LED bulbs, especially those with a regulator in the bulb/panel. Regulators can add RFI interference into your trailer and TV or Stereo may not work.
