Rebaydo 1pc BA15D LED Headlight Dual Filament 6 to 9 Volts Non Polarized Zero Degrees designed for 6 to 9 volt systems with non-polarized operation, making it compatible with both positive and negative ground vehicles. This dual beam LED headlight features a shielded low beam to minimize glare and a powerful high beam output up to 3400 lumens, while the low beam produces up to 1700 lumens. It incorporates CSP LED technology to closely replicate incandescent filament positioning for improved focus and beam pattern. The bulb is constructed from aircraft aluminum for efficient heat dissipation and extended lifespan, with LEDs illuminating on both sides for low beam and all LEDs activating for high beam. Designed with a BA15D dual contact bayonet base featuring even pins, 15mm base diameter, and zero degree contact orientation for correct socket positioning. Dimensions include a maximum overall length of 2.356 inches, diameter of 0.944 inches, heatsink length of 1.595 inches, and width of 0.706 inches. Electrical performance tested at 6 volts shows current draw of 1.6A low and 1.58A high for Warm White, 1.62A low and 1.6A high for White, and 1.6A low and 1.58A high for Daylight White. Available in White 6000K, Daylight White 4500K, and Warm White 3000K, with Warm White closely matching traditional incandescent color. LED efficiency reduces power consumption by up to 90%, easing load on generators or alternators, and load equalizers may be required if headlights blink or do not properly switch between low and high beam. CE and RoHS certified.
