12V / 24V Ba15d LED Bulb – 18 LED Double Contact Bayonet (1142 / SBC)
Upgrade your Ba15d (1142 / SBC) double-contact bulb to this high-output 18 LED bayonet tower, delivering up to 319 lumens while using just 2.4W of power. Designed for 12V and 24V systems, this compact LED replacement is ideal for caravans, motorhomes, boats, classic vehicles, and off-grid lighting. With full 360° light projection and built-in voltage regulation (10–30V DC), it provides bright, efficient, and reliable illumination for wall lights, ceiling lights, and enclosed fittings.
This 18 LED tower lamp is designed as a direct replacement for traditional Ba15d double-contact tungsten bulbs. Its vertical tower design projects light in all directions, making it ideal for fittings where the bulb remains visible or where even room illumination is required.
Despite its compact 46mm overall length, it produces impressive light output while dramatically reducing power consumption — perfect for battery-powered leisure systems.
