But you can swap out the bulb for a 15 or 20 W MR-11 (about $3) and have a great light. I use the NiteRider heads all the time and they are very rugged and nicely weather proof.
Is this just a matter of unscrewing the light to get the housing apart and unplugging and plugging the bulbs? What do you mean by a great light?
I just saw the later posts. Is the housing all you can use? Can't you use the niterider battery pack? Runtime using the Niterider pack?
