The Prevost Le Mirage front turn signal requires a 3057 bulb size while the rear turn signal uses a 1156 bulb size. The replacement chart covers 1990 to 2002 production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Prevost Le Mirage front turn signal uses the 3057 bulb across all listed model years from 1990 to 2002, with the exception of 2001, which does not appear in the specifications.
The 3057 is a dual-filament T25 wedge bulb rated at 12V with a high filament of 27W and a low filament of 7W, conforming to ANSI standards recognized in both the United States and Canada.
The dual-filament design of the 3057 allows it to serve both turn signal and parking light functions within a single housing, which is a common arrangement in front signal assemblies.
The rear turn signal on the Le Mirage uses the 1156 bulb, as specified for the 2000 and 2002 model years.
The 1156 is a single-filament bulb rated at 12V and 21W, fitted with a BA15s bayonet base, and also conforms to ANSI standards for the US and Canadian markets.
The BA15s bayonet base of the 1156 is a single-contact fitting, which distinguishes it from dual-contact bayonet variants and makes it non-interchangeable with those types despite a similar physical profile.
The front and rear turn signals on the Le Mirage use different bulb types, the 3057 and 1156 respectively, and these two bulbs are not interchangeable due to differences in base type, filament count, and wattage.
The 3057 wedge base and the 1156 BA15s bayonet base require different socket designs, meaning a socket built for one will not physically accept the other.
