Rebaydo 2 pcs H13 LED Headlight Bulbs are designed for automotive headlight applications requiring H13 base bulbs, operating on a wide voltage range with no polarity requirement for compatibility with both positive and negative ground systems. Each bulb produces up to approx. 6000 lumens (approx. 12000 lumens per pair) and is not dimmable due to the wide voltage range, with a rated lifespan up to approx. 30000 hours. Built-in cooling fans help maintain optimal operating temperature. These bulbs do not include load equalizers, which are used to simulate the electrical load of incandescent bulbs to prevent hyper flashing or bulb-out warnings. Dimensions are approx. 3.35 inches overall length × approx. 1.94 inches maximum diameter × approx. 1.7 inches bulb length × approx. 1.65 inches base length. Rated for approx. 9V–40V operating voltage, approx. 22.2W per bulb at approx. 13.8V, approx. 1.610A current draw at approx. 13.8V, and approx. 8V start illumination voltage. CE and RoHS listed. 2-year warranty.
