Ensure you select the correct socket type before ordering. Please verify compatibility online or with your vehicle information for assistance. 2. This product fits most vehicles but is not guaranteed to be error-free for all models. If the lights do not function after installation, try reversing the plug by 180 degrees and reconnecting. If flickering or errors occur, this may be due to current differences. Since energy-efficient LED headlights draw less current than halogen or xenon lamps, installing a pair of decoders may be necessary to resolve the issue. Installation precautions: 1. Place the vehicle in park or ensure it is securely in gear. 2. Turn off the ignition and remove the keys. 3. Avoid burns, especially when handling vehicle lighting components. 4. Do not touch the lamp bead with fingers to prevent staining or damage. Do not press the fan to avoid damage. 5. Observe correct polarity. Fully inspect connections at contact points, ports, and wires, as faulty connections may cause lighting issues. 6. Ensure the bulb end does not contact the interior light shield of the headlight during adjustment. Position the wires facing downward. 7. Install a dust cover if available to protect against dust and extend headlight lifespan.
