  When a light bulb is turned on, light moves away from it at speed $c$, by
definition. When light from this bulb illuminates a surface, however, this
illumination front is not constrained to move at speed $c$. A simple proof is
given that this illumination front always moves {\it faster} than $c$.
Generalized, when any compact light source itself varies, this information
spreads across all of the surfaces it illuminates at speeds faster than light.
