G18 BA15S 1CREE 6-30V 18x38.6mm

Elevate your vehicle and marine lighting systems with our premium BA15S LED bulb-a high-performance replacement for traditional G18 incandescent and halogen bulbs, engineered for unrivaled brightness, durability, and versatility. This 1156 LED bulb compact, powerful lighting solution designed for use in boats, cars, RVs, trucks, and even aircraft navigation lights, delivering reliable illumination across every use case.

At the heart of this 1156 LED bulb lies a single ultra-bright CREE LED chip-a hallmark of industry-leading luminous efficiency and color accuracy. Unlike low-grade LED bulbs that sacrifice brightness for size, our P21W LED bulb pumps out an impressive 95 lumens of crisp, focused light, all while maintaining a compact G18 bulb shape that mirrors the form factor of outdated incandescent models. Encased in a clear glass housing, the BA15S LED bulb optimizes light projection with enhanced spotlight performance and a wide illumination range-eliminating dim spots and ensuring maximum visibility for navigation, signal, or marker lighting needs. Whether used as a marine stern light, a car turn signal, or an RV marker light, this 1156 LED bulb cuts through low-light conditions with ease.

Thermal management is a standout feature of this P21W LED bulb. The junction between the glass housing and the metal base features an aluminum heat sink that rapidly dissipates heat generated by the high-power CREE LED chip. This passive cooling system addresses a common flaw in conventional incandescent and halogen bulbs-overheating-while also preventing thermal damage to the LED component. Even with a brightness output of 95 lumens, the protective glass cover of the BA15S LED bulb remains cool to the touch during operation, reducing the risk of burns and ensuring safe handling, a critical advantage for marine and automotive applications where close contact with lighting fixtures is common.

Engineered for universal voltage compatibility, the 1156 LED bulb operates seamlessly across a 6–30V range, making it suitable for 12V automotive systems, 24V truck and marine setups, and even 30V aircraft electrical systems. With a power draw of just 5 watts, it delivers the same brightness as a far more energy-hungry incandescent or halogen bulb while slashing power consumption-extending battery life for boats and RVs, and reducing strain on vehicle electrical systems. The solid-state LED technology also ensures a lifespan of over 50,000 hours, far exceeding the 1,000-hour average of incandescent G18 bulbs, meaning fewer replacements and lower long-term maintenance costs.

Built to withstand harsh environments, the 1156 LED bulb features a shockproof and vibration-resistant design, with a sealed glass housing that protects the CREE LED chip from moisture, dust, and saltwater corrosion-ideal for marine use. The aluminum heat sink also resists rust and oxidation, ensuring long-term performance in coastal or off-road conditions. For pilots, boaters, and drivers alike, this BA15S LED bulb represents a perfect blend of power, efficiency, and durability, redefining what a small-form-factor LED bulb can achieve.

Say goodbye to dim, short-lived incandescent bulbs and upgrade to the reliability of our 1156 LED light bulb. With its high-power CREE LED, advanced heat dissipation, universal voltage compatibility, and multi-application design, it's the ultimate lighting solution for anyone seeking bright, efficient, and long-lasting illumination for their vehicle or watercraft.
