Additional Notes

The Chevrolet Beretta uses the 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across its entire 1987-1994 production run.
Both the 9005 and 9006 are single-filament halogen bulbs operating on a 12-volt electrical system, which is standard for automotive applications of this type.
The 9005 is rated at 65 watts, while the 9006 is rated at 55 watts, reflecting the higher output typically associated with high beam functions compared to low beam.
The 9005 and 9006 bulbs use different base types, P20d and P22d respectively, which means the two bulbs are not physically interchangeable despite their otherwise similar construction.
Both bulbs conform to ANSI standards recognized in the United States and Canada, classifying them within a standardized North American automotive lighting specification system.
The P20d and P22d base designations follow IEC nomenclature, where the number indicates the base contact spacing in millimeters, further reinforcing that the high and low beam sockets on the Beretta are distinct and non-interchangeable.
