1. An electrical apparatus, comprising:

  • a control circuit;

    a switching circuit coupled to the control circuit and coupleable to a vehicular braking indicator, the switching circuit configured to modulate an incoming electrical signal to the vehicular braking indicator to provide a modulated vehicular braking indicator output;

    wherein the control circuit is configured to control the switching circuit to provide the modulated vehicular braking indicator output including;

    upon receiving the incoming electrical signal indicative of an initial brake application, modulating one or more of an output current or voltage provided to the modulated vehicular braking indicator output to vary the apparent intensity of the vehicular braking indicator according to a specified pattern;

    monitoring a duration of the initial brake application; and

    in response, when the duration of the initial brake application exceeds an initial modulation duration, continuing to modulate one or more of the output current or voltage in a manner suppressing apparent variation in intensity but maintaining the vehicular braking indicator output in a manner causing illumination of the vehicular braking indicator.
