For what? Use determines necessity.Do you think off road lights are nessary on Jl Rubicon 2018
Headlights do very little for illuminating tree branches and other low hanging obstacles and such on the trail, so still useful there. Same with obstacles to the edge of the jeep where even the fogs can’t illuminate.
Plus, even just for long distance, great drving lights and high lumen light bars will simply light up more of the off-road than any pair of lights housed in the 7” pods could, so if you want max visibility and don’t need to worry about other vehicles when off-road then they will usually be a plus, the only question is if you ‘need’ it as to whether it’s ‘necessary’ per se.
