    Does anyone know what component or circuit can accomplis this:

    Upon applying the brake, strobe module will cause LED brake lights to flash 4x rapidly for 0.4 seconds and then slowly 4x for 2.6 seconds, then remain in constant on bright mode for as long as brake is applied. Use for LED brake lights & reverse lights only. 1.25 Amp max load.

    The available aftermarket units have multiple flash "modes" to accomodate this.

    This can be done reasonably easily with two 555 timers: use one as a free running flasher and the other is a one shot to power the flasher for a set time interval.
