An indicator light apparatus having two terminals, one of the terminals being connected to the common or ground circuit of an electrostatic spray gun, preferably by connection to a grounded spray gun handle, the other terminal being placed in the proximity of the electrostatic field generated by the spray gun, so as to collect voltage charges emitted from the high voltage electrode of the spray gun and to conduct these charges to ground through the light indicator, which is typically a neon light or the like. The presence of electrostatic high voltage causes sufficient current flow through a light indicator to illuminate the light and provide an indication that the high voltage circuits are operating properly.
