The Peterbilt 210 front and rear turn signal bulbs both utilize a 2057 size. The replacement chart covers 2008 to 2009 vehicle 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 Peterbilt 210 uses the 2057 bulb across both its front and rear turn signal positions for the 2008-2009 model years.
The 2057 is an ANSI-standardized bulb type recognized in both the United States and Canada.
It is a dual-filament bulb, meaning it contains two separate filaments within a single envelope, allowing it to serve more than one lighting function.
The 2057 uses a BAY15d bayonet base, a two-pin offset base design that physically prevents incorrect insertion orientation.
Operating voltage is rated at 12V, consistent with standard automotive electrical systems.
The two filaments draw 26.9 watts and 8 watts respectively, with the higher-wattage filament typically associated with the brighter turn signal or stop function and the lower-wattage filament with a reduced-intensity running light function.
The 2057 is described as a brighter variant of the 1157 bulb. While the two types share the same BAY15d base, the 2057 draws more wattage on its high filament, making them functionally distinct despite their physical similarity.
Because the 1157 and 2057 share the same base type, physical fitment is possible between the two, but substituting one for the other may produce different light output levels than the vehicle was originally designed to emit.
