where I live the biggest night vision problem I have is snow.
I ordered, but not yet installed a light bar from amazon. It has 2 settings, one is white light, the other is yellow light. I hope this helps me out. It would have been cheaper to go with 2 different light bars, one white or one yellow, Fortunately I don't do much freeway driving.
the switch for it is funky, so I ordered 2 toggles, one says light bar one says fogs.
I did hook it to my battery the other night and it is bright in both white and yellow.
I have the fat lip bumper and will be mounting it down low in the lower "grille" area, where the license plate would sit, and Ill have to relocate the license plate
