What is the best combination of lights to provide maximum visibility for responders on scene?

The best combination of lights for maximum visibility for responders on scene is the one that includes red/orange warning lights and headlights while keeping fog lights off. The red and amber warning lights serve to alert motorists to the presence of emergency responders and enhance the visual safety of the scene by drawing attention to it. Using headlights in addition to the warning lights increases overall visibility, making it easier for approaching vehicles to see the responders and the emergency situation.

While fog lights have their specific uses, they can sometimes create glare or reduce visibility in certain weather conditions, which is why they are kept off in this optimal combination. Therefore, having the red/amber lights and headlights on helps ensure that the responders are visible without compromising visibility with fog lights. This approach is particularly crucial in emergency situations, where safety is the top priority for both the responders and the general public.
