Amazon has the best price on those lights.Link to the better price please
My thoughts exactly. Plus if you decide you need more they make a bracket to stack themKC is a good brand however Rigids are a lot better when it comes to quality and durability.
The spots will give more of a narrow beam of light straight in front of the vehicle. The D2 driving lights give you light in front and light off to the side. Check out this video I found on Youtube of the D2 lights.
