Retyping from scratch, just vanished................
Not sure what bulbs you are wanting to change out. Undercabinet recessed reading lamps? These are tiny glass halogen bulbs with two pin contacts. Extremely hot and about 10 watt draw. The LED replacements are round coin style with side pins on them, and draw less than a watt each.
I have converted three RV's so far, different types of bulbs in the different fixtures, but have used M4Products in all of them. I HIGHLY recommend them. They are not the cheapest, but the quality is super, and the color rendition is standardized across the different types of bulbs. I prefer the daylight color, pure white, not blue or yellow. Great for my old eyes. M4 has very good quality stuff, alot of it they engineer themselves and have it made exclusively for them.

The first conversion I didn't know anything so I watched the LED conversion videos by RV Geeks on Youtube and learned alot. The videos are old now but still very useful.

I used the M4 Elite Series. I have had only one bi pin bulb fail, it quit suddenly and I sent it to them and they replaced it quickly.
My current trailer had been converted with cheap LED bulbs that already had failed LEDs on them and the color was all mixed up, so I replaced them with a complete set of M4 bulbs and retained a couple of the old ones to install in outside access storage compartment fixtures where they rarely are used.
