yes, the lights just pull out, but sometimes the springs may get hunk up on the styrofoam insulation, which only means you need to pull harder... but gently... sometimes a twisting motion helps as you pull... and you dont have to remove the light base "cans", to convert to LED.... just replace the bulbs in them...
https://www.superbrightleds.com/ is a dependable place to buy quality LED bulbs, which thay follow a standard when advertising the color intensity and lmen output of what they sell..... its about the cheapest place around to make sure you get what you order.....

for all the "Can" lights in my trailer I bought the
G4, side pin, 390lumen, "natural" color disc lights, and very happy with them.... when i turn on the overhead lights, I want it to be bright like daylight... and it is. if i dont want bright, i will use the mood lighting.....
I also used natural color, LED strip lighting to line the entire perimeter of the under side of the overhead kitchen cabinets, and it was the best improvement, as no matter how bright the interior is, when cooking, there was always a shadow. but not any more....
