Rebaydo 1 pc P15D-30 (2331) LED Headlight Bulb is a dual filament 5–30V DC LED replacement designed for motorcycle and vehicle headlight systems using a 15mm P15D-30 base with a 90° rotated contact configuration specific to 2331-style bulbs. It operates on both positive and negative chassis systems and provides full brightness across a wide voltage range from approx. 5 to 30 volts, making it suitable for older 6V systems as well as modern wide-voltage applications. The lighting pattern uses 1 row of LEDs on both sides for low beam operation, and both rows illuminated together for high beam output for increased brightness and visibility. Rated lifespan is up to approx. 30,000 hours. Load equalizers may be required if flickering occurs or if headlight beam switching does not function correctly, especially in older or corroded sockets, and care should be taken during installation to avoid damaging the retaining ring by forcing the bulb into worn fittings. Operating voltage is approx. 5–30V DC, with current draw at approx. 13.8V of approx. 0.63A on low beam and approx. 0.99A on high beam, and at approx. 6V of approx. 1.57A on low beam and approx. 2.57A on high beam. Dimensions are approx. 2.52 inches overall length, approx. 0.98 inches width, and approx. 1.17 inches maximum ring diameter. This bulb is a NCNRNW which stands for Non cancelable, Non returnable, No warranty.
