OE Replacement: Mitsubishi W3T13271

The Mitsubishi W3T13271 ballasts are original equipment for modern BMW 3 Series (E90/E91) with HID headlights. Headlight ballasts have a limited lifespan and can be costly to replace, often around $400. An affordable replacement ballast is designed to match/exceed OE specs, offering identical function at a lower cost. Replacing both ballasts and bulbs is recommended due to their 2000-hour run time. umnitza has a trusted reputation for providing top-quality automotive lighting products, backed by enthusiasts' expertise and thorough testing, and offers a wide range of options at competitive prices.
