1. A lighting device comprising:
a first lens;
a housing defining a cavity;
a printed circuit board received within the cavity of the housing;
an emitter mounted to the printed circuit board within the housing, the emitter configured to generate light;
a control circuit mounted to the printed circuit board, the control circuit configured to control the emitter based on receipt of one or more messages;
a reflector within the cavity, the reflector configured to reflect the light generated by the emitter toward the first lens; and
an internal optical structure between the emitter and the first lens, the internal optical structure comprising:
a second lens; and
a light shield between the second lens and the emitter, the light shield comprising:
a first surface configured to redirect a first portion of the light emitted by the emitter toward a base portion of the reflector; and
one or more apertures therethrough that are configured to allow a second portion of the light emitted by the emitter to pass therethrough to the second lens,
wherein the redirected first portion of light is reflected by the base portion of the reflector toward and through the second lens.
