Best Premium Output
The Night Breaker 220 is the premium pick when performance matters more than chasing the whitest possible color. It improves low and high beam output while keeping a warmer, weather-friendly stock-style tone.

The CBI-NG is the styling-friendly premium choice. It still performs well, but the main reason to buy it is the cleaner 5300K tone that gives factory HID headlights a more modern white look.

Fitment note: Verify the installed bulb, connector, housing, and factory system before ordering. A bulb-size match is not automatically a conversion recommendation or proof of vehicle-specific testing.
