Additional Notes

The Isuzu Axiom uses the 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across the 2002-2004 model years.
Both the 9005 and 9006 are single-filament halogen bulbs operating at 12 volts, meaning each bulb handles only one lighting function rather than combining high and low beam in a single unit.
The 9005 high beam bulb draws 65 watts, while the 9006 low beam bulb draws 55 watts, reflecting the higher output demand typically associated with high beam operation.
The 9005 uses a P20d base and the 9006 uses a P22d base. These two base types are physically distinct, so the bulbs are not interchangeable between the high and low beam sockets despite their similar appearance.
Both bulb types conform to ANSI standards applicable in the United States and Canada, indicating standardized performance and fitment requirements within those markets.
