13.3 Watt miniature - S8 - 700 Average rated hours - DC Bay base - 12.8 Volt

Reliable Low-Voltage Lighting for Mobile and Specialized Applications

When you are navigating the open road in an RV or maintaining a marine vessel, your lighting needs to withstand more than just darkness—it needs to handle movement and voltage fluctuations. The Satco 13.3-Watt S8 miniature bulb is engineered specifically for 12.8-volt systems, providing a steady, clear light that outperforms standard domestic bulbs in demanding environments. Featuring a rugged C-2R filament, this lamp is built to endure the vibrations common in automotive and maritime travel without flickering or premature failure.

Installation is seamless thanks to the Double Contact Bayonet (BA15d) base. This secure locking mechanism ensures the bulb remains firmly seated in its socket, even when traveling over rough terrain or choppy waters. Whether you are replacing an interior dome light, an indicator signal, or a landscape fixture, the clear finish and 360-degree beam spread provide crisp, omnidirectional illumination that enhances visibility and safety exactly where you need it most.

• Optimized for 12.8V Systems: Perfectly calibrated for RV, automotive, and marine electrical systems to ensure longevity and consistent brightness.
• Vibration-Resistant Design: The specialized C-2R filament is designed to absorb shocks, making it ideal for moving vehicles and heavy-duty machinery.
• Secure DC Bayonet Base: The BA15d base provides a "twist-and-lock" connection that prevents the bulb from vibrating loose during operation.
• Versatile Use Cases: An essential component for interior cabin lighting, instrument panels, backup lights, and high-quality landscape path lights.
• Clear, Reliable Output: Delivers 16 lumens of warm incandescent light with a 700-hour rated life for dependable performance in critical spots.
