You can connect this to a 12 volt batttery dirrectly or to a 12 volt male plug to plug into a ciggarrete lighter bay ( which is what I ultimately choose to do). Very bright light! I have a very long amount of wires connected to a cig lighter adapter, the result is i can use it at will while driving looking for deer and coyote's or I can set it on something and use it to illuminate a very large area wit ALOT of light. Great flood light but it does drain down the battery very fast.
