The Mitsubishi Raider front turn signal requires a 3157NA bulb size while the rear turn signal uses a 3157 bulb size. Replacement chart data covers 2006 to 2009 model years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Mitsubishi Raider uses the 3157NA bulb for the front turn signal across all documented model years, 2006-2009.
The 3157NA is an ANSI-standard dual-filament wedge bulb in the T25 form factor, rated at 12V with a 27W high filament and a 7W low filament. The "NA" designation indicates natural amber-tinted glass, which produces an amber output without relying on a colored lens.
The rear turn signal on the Raider uses the 3157 across the same 2006-2009 model year span.
The 3157 shares the same ANSI-standard T25 wedge form factor and 12V, 27W/7W dual-filament configuration as the 3157NA, differing only in the absence of the natural amber glass coating.
Because the 3157 and 3157NA share the same physical form factor and electrical ratings, they are mechanically interchangeable. However, substituting a clear 3157 in place of a 3157NA at the front position would alter the amber color output if the housing lens is also clear rather than amber-tinted.
The dual-filament design of both bulb types means each serves two functions within a single housing, with the higher 27W filament typically active during signaling and the lower 7W filament used for a secondary function such as parking or running light duty.
