IMHO, it's not essential that one has LEDs.
However, here are some thoughts you might consider.
Standard incandescing lights draw much more power, are hot, provide a different color temp, are generally omnidirectional, less costly, easier to acquire, less sensitive to voltage difference (over and under), and more resistive to static crashes (lightning). Heavier wire is necessary, vs LED wiring.
LEDs are costly in comparison, are not hot, come in natural, cool white, and bright white as well as blue, yellow, red, orange, etc. They, as a rule, more directional, and most often are supplied with bases that fit into conventional sockets.
So, if your RV doesn't come with them, it doesn't matter. Simply purchase these from a supplier, replace the original bulb, keep that one on hand as a replacement in case.
Do I like LEDs: answer- absolutely. We've had them over the last 10 years, when I had to make the array myself, adding current-limiting resistors and manufacturing the housing.
If you camp without AC power for longer periods and don't want to start a generator, the LED will keep you lit for a long period. A 12w standard light on a 12v system uses 1 amp per hour. Therefore, 4 standard lights for 8 hours (night) means you've consumed 4 x 8 = ? amps. P=IE (power in watts = current x voltage)
Since your battery has X total amp hours, and the maximum discharge is 50%, even though you should consider no less than 75 ah remaining, then, how many hours can you use 4 lights?
If the ambient temp is hot, such as the southern comfort zone, then, your standard lights will increase your temp, too.
Because LED technology is much better than 10 years ago, you'll not need to make your own lighting. These lights cover more area, are brighter than those last decade, etc. And, the LED will last longer, certainly a thing of the future.
Because we camp in all conditions, the LED is our first choice, even in flashlights.
But, if you are always camping with AC in colder weather, have these already, -- so what?
