Cutting Through the PNW Soup: The Physics of Amber Off-Road Lighting.

The most common—and arguably most dangerous—mistake new truck owners make is bolting a massive, cheap 50-inch light bar to the roof of their rig. It looks aggressive in a parking lot, but the first time you flip that switch on a wet, foggy November night in the Olympic Mountains, you are instantly blinded by a solid, impenetrable wall of white light. It is a harsh lesson in off-road physics: raw lumen output means absolutely nothing if the light isn't usable.
