SWPHRT 2PCS 12V 35W Car Xenon HID Ballast, Ultrathin Vehicle Xenon Lamp Ballast, Waterproof Automotive Headlight Stabilizer Replacement Accessories, Suitable for H1 H3 H4 9005

Premium Material: This bulb ballast is manufactured from high-grade aluminium, selected for its exceptional durability, corrosion resistance and superior heat dissipation properties – characteristics vital for withstanding the high-temperature environments inherent in bulb lighting systems. Aluminium efficiently absorbs and disperses heat generated by gas discharge, maintaining internal components at optimal temperatures even during prolonged operation.

Universal Fit: Measuring 3.27 x 2.53 inches, its compact design ensures no interference with other components. It offers broad compatibility with most H-series and 9000-series bulbs: H1, H3, H3C, H4-1, H4-2, H7, H7C, H7R, H8, H9, H10, H11, H13, H13-2, 9004, 9004-2, 9005, 9006, 9007-2. This universal compatibility allows you to freely select your preferred bulb type, making it an all-purpose solution for cars, trucks, SUVs, and more.

Easy Installation: Installation is remarkably straightforward, requiring no wiring modifications or technical expertise. Follow these steps: First, switch off the vehicle's engine and disconnect the negative battery terminal for safety. Disconnect the old ballast from the headlight bulb and vehicle wiring harness, then remove all mounting brackets. Connect the ballast to the bulb and vehicle wiring harness. Reconnect the battery and switch on the headlights to verify operation.

Safety Feature: This ballast enables the bulb to achieve a 50,000-hour lifespan, significantly reducing replacement frequency. Furthermore, it supports 8,000 lumens of light output, with bright illumination enhancing night-time visibility, expanding the driver's field of view and reducing visual fatigue. Featuring a gradual safety fade-out design, should the bulb malfunction, it will not extinguish abruptly but dim gradually.

Packaging Includes: This product comes in a bagged package, each set containing two premium aluminium bulb ballasts sufficient for upgrading both front headlights. The dual ballast bundle provides a complete headlight solution, eliminating the need to purchase left and right units separately, making it an efficient, convenient, and practical choice for bulb lighting upgrades.
