Can't find anything on the second one, but the other seems to have been recorded by a large number of performers. Wilma and Stoney Cooper for one, Tex Ritter for another. It was written by Frank "Hylo" Brown.

When It's Lamp Lighting Time In The Valley
Frank "Hylo" Brown

Oh there's a lamp shining bright in a cabin
In a window it's shining for me
Then I know that my mother is praying
For the boy she is longing to see
 
Chorus
When it's lamp lighting time in the valley
In my dreams I go back to my home
Oh I can see that old lamp in the window
It will guide me wherever I roam
 
Oh when the lamp lights tonight I can see her
As she rocks in her chair to and fro
Though she's praying that I'll come back to see her
And I know that I never can go
