Additional Notes

The Ferrari 348 TS uses the 9005 bulb for high beam headlights and the 9006 bulb for low beam headlights across the 1989-1992 model years.
Both the 9005 and 9006 are ANSI-standardized halogen bulbs, meaning their specifications are regulated for the United States and Canadian markets.
The 9005 is a single-filament halogen bulb rated at 12V and 65W, fitted with a P20d base, and serves the high beam function in this application.
The 9006 is a single-filament halogen bulb rated at 12V and 55W, fitted with a P22d base, and serves the low beam function.
Although the 9005 and 9006 share the same voltage rating, the 9005 draws 10 more watts than the 9006, producing a higher-intensity output suited to high beam use.
The P20d base on the 9005 and the P22d base on the 9006 are physically distinct, which means the two bulb types are not interchangeable despite their similar appearance and shared voltage rating.
