Original equipment headlights vary by model but average a reflective range of 4000-5000'. Warn 6" and 5" 4X Spot lights project an intense pencil beam with a reflective range of 10800' and 7900' respectively. Understandably, they are designed exclusively for off-road use, as such a powerful beam would be blinding to oncoming traffic on the street. 4X Spot lights are built to last. They're equipped with resilient 100 watt H-3 quartz halogen bulbs encased in polished stainless steel and come with virtually impenetrable lens covers. A 2-axis mounting bracket allows for easy adjustment. Lights are sold separately, or in kits.
