Best Standard Reflector Upgrade
The Night Breaker 200 is the top standard-wattage reflector recommendation at the time of review. Anything scoring higher in the reflector chart uses much higher wattage, while the NB200 keeps the simple drop-in halogen format.
A matching bulb size identifies fitment; it does not by itself prove optical compatibility or make a conversion a vehicle-specific recommendation.

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.

Other Audi A3 years
Each model year opens its own BulbFacts record. Bulb sizes and factory systems are not carried over from adjacent years.
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.
