Buying advice

When choosing headlight or taillight conversion kits, ensure the bulb size (e.g., H11, 1157) matches your vehicle. For LED headlights, prioritize beam pattern and cooling over raw lumens to avoid blinding others and ensure longevity. Check vehicle compatibility and any resistor requirements to prevent hyper flash. Budget options work but may have shorter life or less brightness; premium kits offer better performance and reliability.
