Additional Notes

The Ferrari 512 TR uses the 9005 bulb for high beam headlights across its 1992-1994 model years. This bulb follows the ANSI standard applicable in the US and Canada.
The 9005 is a single-filament halogen bulb rated at 12V and 65W, fitted with a P20d base. The single-filament design means it serves one lighting function only, in this case high beam output.
Low beam headlights on the 512 TR across the same 1992-1994 span use the 9006 bulb, also an ANSI-standardized halogen type for the US and Canadian markets.
The 9006 operates at 12V and 55W, drawing 10 watts less than the 9005. It carries a P22d base, which differs from the P20d base of the 9005.
The base type difference between the 9005 (P20d) and the 9006 (P22d) means the two bulbs are not physically interchangeable, despite sharing the same voltage rating and a similar single-filament halogen construction.
Both bulb types are governed by ANSI standards, which define consistent electrical and physical specifications to ensure uniform performance and fitment across compliant products.
