After searching, I found many suggestions regarding types of marker beacons. What I would like to see would be something a bit more basic. Think of a lighthouse or airport marker. A craftable light beacon that visibly appears in the world up to say 500 blocks or more (unobstructed). Imagine being able to cross ocean biomes, or large desert/plains areas without the use of maps, mods, or f3. Another example comes to mind with LOTR's warning fire beacons. This would greatly help those of us who play "vanilla" but think leaving a trail of red wool (et al) is a bit ridiculous.
