The Lamborghini Jalpa high beam and low beam headlight bulbs both utilize a 9003 size. The replacement chart covers vehicle production spanning 1982 to 1988.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Lamborghini Jalpa uses the 9003 bulb size across all listed model years (1982-1988) for both high beam and low beam headlight positions.
The 9003 is a dual-filament halogen bulb, meaning a single bulb contains two separate filaments to serve both the high beam and low beam functions within one unit.
Because the 9003 handles both beam functions in the Jalpa, the high beam and low beam headlight positions share the same bulb specification rather than requiring separate part numbers for each function.
The 9003 operates on a 12-volt electrical system and carries a wattage rating of 60W on the high beam filament and 55W on the low beam filament.
The 9003 uses a P43t base, which is a standardized bayonet-style socket type that determines physical fitment into the headlight housing.
The 9003 is an ANSI-standard bulb recognized in the United States and Canada, meaning its electrical and physical specifications conform to a defined North American standard.
The 9003 and H4 bulb types share the same dual-filament design and P43t base, making them functionally interchangeable in many applications, though fitment should be confirmed against the specific housing before substitution.
