Lunasea G4 10 Back Pin LED Light Bulb - 12VAC or 10-30VDC/2W/140 Lumens - Warm White

The Lunasea G4 10 Back Pin LED Light Bulb is a compact, mission-critical lighting solution engineered for auxiliary vehicle applications where reliability and efficiency matter. Designed for both 12VAC and 10-30VDC systems, this bulb fills a critical gap in aftermarket automotive lighting—whether you're upgrading interior map lights, dome lights, courtesy illumination, or auxiliary dash indicators on trucks, RVs, boats, or off-road vehicles.

The warm white output eliminates the harsh glare of traditional incandescent bulbs while consuming minimal electrical load, making it ideal for battery-conscious installations or vehicles with limited electrical capacity. This LED retrofit delivers 140 lumens at just 2 watts—roughly equivalent to a 15W incandescent while drawing less than 20% of the current. The G4 ten-pin back-pin configuration ensures direct compatibility with OEM and aftermarket G4 sockets without modification.

Mechanics and enthusiasts upgrading RVs, marine vessels, agricultural equipment, and custom trucks benefit most from this bulb's voltage tolerance and low power draw. The dual-voltage design (10-30VDC + 12VAC) handles voltage fluctuations common in vehicles with alternator issues or extended battery drain scenarios. The warm white color temperature (typically 2700-3000K) provides visibility without the blue-spectrum glare that fatigues vision during nighttime driving.
