Additional Notes

The GMC Envoy XUV uses the 9005 bulb for high beam headlights across both the 2004-2005 model years.
The 9005 is an ANSI-standardized single-filament halogen bulb rated at 12V and 65W, fitted with a P20d base.
Low beam headlights on the Envoy XUV use the 9006 bulb across the same 2004-2005 model year span.
The 9006 is also an ANSI-standardized single-filament halogen bulb, rated at 12V and 55W, but carries a P22d base rather than the P20d base found on the 9005.
The base difference between the 9005 (P20d) and 9006 (P22d) means the two bulbs are not physically interchangeable, despite sharing the same voltage rating and a similar form factor.
Both the 9005 and 9006 are recognized under ANSI standards applicable in the United States and Canada, meaning they conform to a defined set of electrical and physical requirements within those markets.
The 10-watt difference between the high beam 9005 (65W) and the low beam 9006 (55W) reflects the greater luminous output typically associated with high beam operation.
