Extra truck lighting is essential for overlanding as it provides better visibility and increased safety in low-light or dark conditions. By adding extra lighting, drivers can improve their peripheral vision, increase their reaction time to obstacles and wildlife, and avoid potential hazards on the road. Extra lighting options include fog lights, driving lights, and spotlights, which can be mounted on the front or rear of the vehicle. Additionally, light bars can be installed on the roof or hood of the vehicle for enhanced illumination of the surrounding terrain. Brighter lights can also deter wild animals and enhance the security of the campsite. Overall, adding extra lighting to an overland vehicle is a crucial upgrade for ensuring safe and successful travel in any condition.
