what addon can highlight a bar button when something proc?

for example to highlight the Maelstrom weapon proc, lighting bolt to be highlighted

(Maelstrom weapon = When you deal damage with a melee weapon, you have a chance to reduce the cast time of your next Lightning Bolt, Chain Lightning, Hex, or any healing spell by 20%. Stacks up to 5 times. Lasts 30 sec.)

i dont speak about text warnings on screen
