The Mitsubishi Endeavor parking light uses 1157NA and 1034NA bulb sizes for the lighting components located on the front of the vehicle. Data for the specific bulbs covers the period from 2004 to 2011.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The front parking light position on the Mitsubishi Endeavor uses two bulb types across its production years: the 1157NA and the 1034NA, both of which are ANSI-standardized dual-filament bulbs rated at 12V with a 21W/5W output.
Both the 1157NA and 1034NA share the BAY15d bayonet base, a two-pin offset base design that physically locks the bulb into the socket with a twist.
The natural amber glass in both bulb types produces a color-filtered output without the use of a painted or coated lens, which is reflected in the "NA" suffix of each part number.
The 1034NA is classified as a variant of the 1157NA, meaning the two types are related in design but are not confirmed as interchangeable without verifying the specific year and socket fitment.
The 1157NA is specified for the Mitsubishi Endeavor front parking light across the 2004-2011 model years, with 2009 not represented in the data.
The 1034NA appears in the front parking light position for the 2004, 2005, and 2010 model years, while the remaining years in the dataset use the 1157NA for that same position.
The dual-filament construction of both bulb types means each bulb serves two lighting functions within a single housing, with the 21W filament handling the higher-intensity function and the 5W filament handling the lower-intensity function.
Because the 1034NA and 1157NA share the same BAY15d base, physical installation is possible with either type, but wattage and filament characteristics may differ in ways that affect circuit compatibility.
