light LED Car Bulbs,Plug And Play, Pack of 2 | 3570 Chips H7 K11-3570-H7

【POLARITY INSTALLATION TIP】 H7 bulbs are polarity-sensitive. If a bulb does not illuminate after installation, remove it, rotate the connector 180 degrees, and reconnect it. The all-in-one design integrates the driver into the bulb body, eliminating the need for an external decoder and allowing the factory dust cap to close securely without modification.
