Additional Notes

The Honda CRX uses the 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across the 1988-1991 model years.
Both the 9005 and 9006 are ANSI-standardized halogen bulb types recognized in the United States and Canada, meaning they conform to a defined set of electrical and physical specifications shared across manufacturers.
The 9005 is a single-filament halogen bulb rated at 12V and 65W, fitted with a P20d base, and is designated for high beam use in this application.
The 9006 is a single-filament halogen bulb rated at 12V and 55W, fitted with a P22d base, and is designated for low beam use. Its lower wattage relative to the 9005 reflects the reduced light output typical of low beam configurations.
The P20d and P22d base types are physically distinct from one another. Despite the visual similarity between the 9005 and 9006, the differing base configurations mean the two bulbs are not interchangeable between the high and low beam sockets.
