Precision Low-Voltage Performance: Single Contact Bayonet Base LEDs

Upgrading your low-voltage lighting systems requires a balance of durability and clarity. Our collection of Single Contact Bayonet Base (BA15s) LED bulbs is engineered specifically for 12-volt applications where space is often limited but light output is critical. These bulbs feature a secure twist-and-lock mechanism that ensures consistent electrical contact even in environments prone to movement or vibration. By replacing power-hungry incandescents with high-efficiency LED alternatives, you significantly reduce the load on your battery or transformer while benefiting from a cooler operating temperature and a much longer lifespan.

Whether you are maintaining a recreational vehicle, updating marine cabin lighting, or enhancing a residential landscape design, these BA15s bulbs provide versatile solutions. The clear finish on our T6 and Mini LED models allows for maximum lumen transmission, making them ideal for reading lamps or task lighting where visibility is paramount. Meanwhile, specialized options like the 3000K R12 LED offer a warm, inviting glow that mimics traditional halogen bulbs without the excessive heat or frequent burnouts.

• RV and Motorhome Interiors: Perfect for ceiling domes, closet lights, and reading nooks where a compact form factor is essential for tight spaces.
• Marine Applications: Reliable illumination for boat cabins, bait wells, and accent lighting that stands up to the demands of off-grid power systems.
• Landscape Fixtures: Durable enough for outdoor path lights, step lights, and garden spotlights integrated with a 12V transformer.
• Specialty Automotive: Suitable for specific interior and utility lighting in classic cars, trailers, and heavy equipment requiring a BA15s base.

Choosing the right bulb involves matching the specific envelope shape to your fixture’s housing. Our selection includes the slim T6 profile for narrow glass enclosures and the classic R12 shape for directed beams. With wattages ranging from 3W to 4.5W, these LEDs provide the equivalent brightness of much larger incandescent bulbs, allowing you to brighten your environment while conserving energy and reducing maintenance cycles.
