fairly easily. gain access to rear of gauge module...unplug and remove entire assembly from its mounting points. it is totally electronic so no driver cable ends to uninstall. after removal you then place it gauge side down onto soft towel atop work bench...unscrew the fasteners on back which exposes inner workings and the plug in LED bulbs. the only source i ever found for the bulbs is american sportbike though other board members might have another source. as memory serves me there are 5 clear LED bulbs for the guages themselves....then several more for the warning lights.
