Do you know who you are?

Late last night, a searchlight
I saw a ball of fire streak across a midnight sky
I watched lower and lower, shrink and sink into
Into the silhouette morning
It wants to die

I said "hey, you know I've got
A lot in common with that light, alright"
Like a light with a fire
My life streaks across my span of time
As seen by those who live their lives
In search of light to help them
Through the long, dark, night, right
