Additional Notes

The Infiniti M30 uses the 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across the 1990-1992 model years.
Both the 9005 and 9006 are ANSI-standardized halogen bulbs rated for use in the United States and Canada, each operating on a 12-volt electrical system.
The 9005 is a single-filament halogen bulb rated at 65 watts, making it the higher-wattage of the two bulb types used in the M30's headlight system.
The 9006 is also a single-filament halogen bulb but is rated at 55 watts, reflecting its role in the low beam position where less output is required.
Although the 9005 and 9006 share a similar physical profile, they use different base types. The 9005 uses a P20d base while the 9006 uses a P22d base, making the two bulbs non-interchangeable despite their visual similarity.
The difference in base type between the 9005 and 9006 is a deliberate safety measure under the ANSI standard, as it prevents a higher-wattage high beam bulb from being installed in a low beam socket.
