Keep rack service fast and accurate with a replacement headlight assembly built for Furman RL LED series rack lights. The 391355-3994 runs on 12 V and uses a flexible goose neck to place light where it matters most, reducing shadows across patch panels, controls, and rear connections. Four LEDs provide crisp, efficient illumination without adding unnecessary bulk to the rack. That matters in professional audio, video, and live sound environments where technicians need immediate visibility during setup, troubleshooting, and late-night changes. The compact assembly is designed for direct integration into Furman rack systems, helping preserve the fit and finish expected in premium installations. For teams maintaining high-value racks, this is the kind of replacement part that protects uptime and keeps service work clean. It is a practical choice when you need the original lighting behavior back without replacing the full rack light assembly.
