How to Illuminate Your Jeep Undercarriage for Night Crawling storeboard.com
It's vital to understand how rock lights integrate with your primary headlighting system. Your Jeep LED headlights are for distance and general forward projection; they cast long shadows directly underneath the Jeep. Rock lights are the complementary tool that fills in those shadows, illuminating the "V" of darkness created by the hood and fenders. In practice, you would use low-beam headlights combined with fog lights (for foreground) and rock lights (for undercarriage) during slow, technical crawling. This layered approach provides complete 360-degree situational awareness without any single light source creating blinding glare or deep shadows. Your rock lights should be on a separate circuit from headlights, allowing you to activate them independently when stopped to assess an obstacle or work on the trail.
