Firstly, on the harness: it is not included. That is not really a minus for me since like a lot of users I have my own set of aux lighting switches in a switch pod. Rather than include the cost in this light bar and charge everyone, including those with no need for a harness ten beans more to include a harness, you have the option of buying the harness separately, it is nine bucks here on amazon.On the light: The beam pattern of this is a very good and useful mix of spot and flood. It is very bright and has quite a reach with its 200 watts (~17 amps at 12 volts). The construction looks good and it is (self) rated by Nilight at ipx68, which means it is supposed to withstand total immersion over a long period of time. Now UV, vibration and heat from a light take their toll on seals, and I can only say that time will tell how long this is properly waterproof.The mounting system is versatile with both side mount and bottom mount. The bottom mount system is a bit tricky to get going, but once you have it in it allows you to use preexisting mounting tabs/holes that may be on your bumper or pushbar of various distances apart.
