Not the best with electricity so looking for some advice. The kit I was told to run on my bike will run me around $450. Was wondering if I can make this number a bit lower by buying a light getting a battery of some sort preferably lightweight and able to work well in cold conditions as it will mainly be used in the winter on a timbersled. Would like at least 4hrs of run time out of the light. I would like to have the light bright enough to light out around 60 feet if possible. Any recommendations on a light bar and battery that word do this for me? Thanks
