Reliable 14V Illumination for Precision Environments

When your operations depend on clear visibility in specialized settings, the SATCO 3.78-watt miniature bulb delivers consistent, professional-grade performance. Specifically engineered for 14-volt systems, this G4-1/2 lamp is a staple in the aviation and industrial sectors where dependable lighting is non-negotiable. Whether you are maintaining sensitive cockpit displays or ensuring industrial indicator panels remain functional, this bulb provides the sharp clarity required for safety and operational efficiency.

The design focuses on durability and ease of maintenance. Featuring a Miniature Bayonet (BA9s) base, the bulb utilizes a secure twist-and-lock mechanism. This ensures that even in high-vibration environments—such as an aircraft in transit or heavy machinery on a factory floor—the connection remains stable and the light stays on. The clear incandescent finish offers a crisp light output, while the C-2F filament is built to withstand the rigors of frequent use and electrical fluctuations.

• Compact Form Factor: The small G4-1/2 profile allows for seamless integration into tight housings and specialized glass lenses where space is at a premium.
