Is the smudge pot just to keep snow accumulation off the sign?
Yep, the Texas highway contractors used them in the 40s and 50s too. I remember that a crew (like your grandfather) would fill them with kerosene and light them every evening right before dark. Most would burn all night warning drivers of highway pavement drop offs, dirt and gravel stock piled along the road way, highway signs in construction zones, etc.
The Deitz battery operated blinking yellow lights replaced them by 1960.
