If you go to the M4 site they have a tutorial on each of the different style and model bulbs.
There's also a page that shows the color difference between, warm, daylight, and cool bulbs.
We switched all the interior bulbs on our 2013 Adventurer to LED's this summer. We purchased the Samsung Elite series daylight bulbs from M4 Products and have been very pleased with the results. They will allow you to open 1 package of each style you order for test purposes. If you don't like the fit or color you can return all of them.
I guess I don't understand the advantage of replacing the exterior marker and directional bulbs. The only time they're on is when you're driving. The 175 amp alternator is spinning and generating electricity, so there's no battery drain. The minor amount of current saved is a mute point when considering the additional cost involved.
I know the LED's are supposed to last longer than the incandescent, but we put over 100,000 miles on our last coach and only had to replace a couple headlights. When we traded it off last year it still had all the other original exterior lamps.
