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.

A matching bulb size identifies fitment; it does not by itself prove optical compatibility or make a conversion a vehicle-specific recommendation.
