I do like the looks of these lights, and the 5,000 lumen light would be pretty bright. But the existing light is 35 watts, so i doubt that the alternator could handle these 72 watt lights. But, im actually pretty happy with the factory lighting. I have noticed that while pushing or blowing snow at night, the existing lights reflect too much light off of the falling snow, and actually bugs me with the reflection. I would like to know how the bright LED's handle during actual snow plowing work during the storm. I have to clear snow after it reaches 6" no matter if its still snowing or not, so waiting for daylight isnt an option.Anyone here actually use these lights under these conditions yet? I have to say i have been impressed with the Whelen L31 that i installed a few years ago. As far as strobe lights go, this one is incredibly bright. I have it mounted up high enough that i have not had any problems with snow accumulations yet.
