Before I bring in the lights

Something new,

 at least worth a try.

Our little lightshow,

 shared with the neighbors.

Tinkerbell flying across the garage door,

  backed by a scattering of snowflakes.

Sadly,

 the show is unable to play throughout the night,

   simply because in the morning it might be gone.

So,

 I let the visions play,

  at least until I grow tired.
