1. A removable illumination source configured to attach to a mount within a headlamp assembly of a vehicle, said vehicle including a power conductor and a ground conductor, said headlamp assembly including a reflector having a focus, comprising:
(a) a plurality of light emitting diodes, mounted on a frame having a base configured to engage said mount and a shank region proximate said base;
(b) driver circuitry configured to take in power from said power conductor of said vehicle and provide suitable power to drive said plurality of light emitting diodes;
(c) a controller configured to control said driver circuitry in order to vary a light output of said plurality of light emitting diodes;
(d) said controller being configured to wirelessly communicate with a separate command device so that said output of said plurality of light emitting diodes is responsive to a command sent by said separate command device;
(e) a subset of said light emitting diodes being mounted on said shank region of said frame to the rear of said focus; and
(f) said subset of said light emitting diodes being independently controllable by said controller.
