An apparatus and associated method for mounting a device beneath the brim of a helmet. The apparatus defines a passageway that is sized to receivingly engage the device, and further defines an aperture pattern arranged to align with a preexisting threaded fastener pattern on the helmet to operably position the bracket beneath the brim not extending substantially beyond an outer edge of the brim. A flexible portion of the apparatus is selectively engageable to transmit a force to the flexible portion of the bracket to operably reduce the size of the passageway and thereby frictionally affix the bracket to the device.
