The Booster Glow is a module of the Boosting locomotion; it provides a particular functionality for its parent Booster. If it is disabled or removed, then the relevant boosting functionality will behave as by default. Most modules can optionally affect change globally (for both hands' Boosters). Booster modules can also depend upon conditions specified by their dependencies settings.
This module uses the BoosterFlickerer class to control a light that flickers in intensity. The flickering is according to what the intensity range and intensity increment range values are set to.
