Best HID Color Match
The Cool Blue Advance is another color-focused pick, not a maximum-output pick. It makes sense when matching the look of other whiter lighting is more important than measured brightness.

Best Premium Distance
The Morimoto XB Elite remains the premium performance benchmark from the current HID recommendations. It tested as one of the strongest 35W projector-focused HID kits and is the better fit when you want a complete, higher-quality conversion kit instead of a generic marketplace option.
A matching bulb size identifies fitment; it does not by itself prove optical compatibility or make a conversion a vehicle-specific recommendation. Use the LED upgrade path only with a reflector housing and confirm beam pattern and glare after installation. Use the HID upgrade path only with a projector housing; it is not a reflector-housing recommendation.

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.
