I'm doing a dual sport light kit on my 07 WR450 and will be getting the light certification somewhere. I understand the tail light goes on when the ignition button is pushed and that the head light runs of AC when the motor is going. My question is .... Does the light certification require the HEADLIGHT to also be able to stay on 15 minutes? Since the blinkers, taillight, brake light run off the battery that is no problem, but what if the head light is required to run of DC, would I just bypass the existing wiring to the front light, t then hook up to the battery? And if so, I'm assuming the battery won't be enough power to run an stock AC headlight unless I change the filiment to a DC type. Any one got any suggestions or knowledge.... If the lighting cert only requires the tailight to stay on 15 minutes then I will just keep the head light stock and wire for the hi/lo beam from the existing AC power to it.
