Adds a little 'glow' to electric miners, assembling machines, chem plants and oil refineries, to make the factory more visible at night. Not intended as an complete replacement for lamps - think of it more like an LED display panel glowing. A brighter glow is visible when the machines are working - more like sparks flying from a whirring assembler machine.

Helps navigation through parts of the factory you might have forgotten to build lamps in :)

Supports Bob's and Angel's mods, and includes a new glow effect during the working animations for Electrolysers (it bothers me that the sparks don't give off any light), Induction Furnaces and Casting Machines (molten metal does tend to glow :) )
