The blue core present in vanilla model now has an aura surrounding it (similar to the one seen in redstone torch), and it has also been made emissive, to better sell it imagine of a glowing core within the casing.

The casing as also be changed with the obsidian base being widened, This was done to add "slots" on the sides of the block, representing where the items would be inserted to activate the beacon.
