Engineered Reliability for Heavy-Duty 28V Applications

When your equipment operates on a specialized 28-volt system, you cannot rely on standard automotive bulbs. The SATCO S8 Miniature Bulb is precision-engineered for the rigorous demands of aviation, marine, and heavy-duty industrial machinery. Whether you are maintaining a commercial aircraft cabin, upgrading transport trailer indicators, or servicing specialized manufacturing equipment, this bulb provides the consistent 32-lumen output required for safety and operational clarity.

Durability is at the core of this bulb’s design. Featuring a rugged C-2V filament, it is built to withstand the constant vibrations and movement common in mobile and mechanical applications. The Bayonet Single Contact (BA15s) base ensures a secure, "lock-in" fit that stays put, eliminating the risk of the bulb shaking loose during operation. With its crystal-clear finish and 360-degree beam spread, you get full-spectrum visibility that eliminates dark spots in critical areas.
