BulbFacts testedCorrect bulb size
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.

Technical details and sources
Fitment, factory-system research, and BulbFacts product tests remain separate evidence. A matching bulb size does not by itself make a conversion a vehicle-specific recommendation.

Other GMC Yukon 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.
