Light Up the Night
Hibernating when it is cold,
But when it is warm I become bold;
I light up the night,
For every child`s delight.
Some people I might annoy
But to others I bring joy.
What am I?
Note, I find this riddle to be pretty vague. I wouldn't be surprised to find multiple answers are possible.

Not a Plant
Though not a plant,
Has leaves.
Though not a beast,
Has spine.
Though many wouldn't need this thing
'Tis more valuable than wine.
What is it?

Stars Awash in a Sheen of Light
Stars awash in a sheen of light
It calls out loud in vile delight.
Listeners endure in fright.
Vicious brute that reigns at night,
Evil whelped of heinous bite,
Renewed by wax, it regains might.
A leading way to slay the beast,
Get the hidden weapon thus released.
Got this one and a couple of others from dan hersam. The answer is there if you can't wait for someone to post it here.
