Can we honestly believe that the light from a streetlight or neon sign will be enough to stretch all the way up into the atmosphere?

Compare these with the laser shows which pump out far more power AND they are directed energy.
Streetlights shine downwards, and neon signs are not directed upwards either (no-one up there to see the advertising).
I think the explanation that these are caused by streetlighting and neon advertising signs is stretching our belief somehow.

Columns of light apparently beaming directly upwards from unshielded (and wastefully polluting) lights are sometimes visible during very cold weather. Plate shaped ice crystals, normally only present in high clouds, float in the air close to the ground and their horizontal facets reflect light back downwards.
