Sticky Flares

Potential to help solve lighting issues in large caverns. Flares could be timed, lasting for 20 minutes for example. Flares could be shot from a crossbow and stick to whatever surface they contact. Flares could provide a very bright light source that has a very broad reach. Say 50 blocks for example. Flares could be crafted from various ingredients such as rockets, slime balls and more ingredients and have a limited travel range like arrows. This could help solve lighting problems for very large areas at least temporarily while permanently lighting is being installed or while the player is mining. These could also be fun for other aspects of game play such as signaling players from a distance and using the spyglass to investigate.
