For the first time a smile lit her whole face.

Her smile could light my life, or break my heart.

A smile suddenly lit her face, which should have given him fair warning.

A man's smile can light me up when he talks.

He was quiet for a moment, then a bright smile lit his face.

She looked up and saw him, a small smile lighting her already lovely face.

She leaned over to look and a smile lighted her face.

A smile lit on her features as she went into his arms.

A smile lit her face, full of fun, when he hadn't expected it.

A smile lit his features when he saw who it was.
