How many watts is a 700,000 candlepower spot. If it is less than the highbeam wattage of the trike, then you could power it with the headlight off. The honda trike stators were pretty closely matched to the load requirements, so adding any significant load will toast the stator. There are higher power stators available, one source I know of is www.rickystator.com
