BA15s Bayonet Base

Single Contact Bayonet (BA15S) LED Bulbs

High-performance Single Contact Bayonet LED bulbs, featuring the common BA15S base. Characterized by its single contact point at the bottom and two parallel locking pins, the BA15S base is a direct replacement for traditional incandescent bulbs like the 1156 and 1141. These bulbs are a versatile choice for a wide range of 12V applications, from landscape lighting to RV and automotive use.

Upgrading to our LED versions offers incredible benefits: dramatic energy savings, a lifespan that is thousands of hours longer than halogen, and solid-state durability that resists vibration and shock.

Finding the Right BA15S Bulb:

  • For Your Landscape: Look for our IP67 waterproof models in the classic S8 globe shape. They are fully sealed to stand up to rain, sprinklers, and damp conditions, making them the perfect fit-and-forget solution for path and area lights.

  • For Your RV or Boat: Our low-wattage options reduce the strain on your 12V battery system, while the durable LED design ensures your lights keep working on bumpy roads or choppy water.

  • For Superior Light Quality: Choose a lamp with advanced COB (Chip-on-Board) technology for a smooth, uniform glow without the spotting effect of older LEDs.

Whether you're a contractor outfitting a landscape project or an enthusiast upgrading your vehicle, our BA15S LED bulbs offer a reliable and efficient solution.
