Additional Notes

The Freightliner MB Line uses the 1159 bulb for its back up light across the 1995-1997 model years, with all listed entries specifying the Cab Over Engine configuration.
The 1159 is an ANSI-standardized bulb recognized across the United States and Canada, meaning it conforms to a defined set of electrical and physical standards shared across manufacturers.
The 1159 is a dual-filament bulb, meaning it contains two separate filaments within a single envelope, each serving a distinct lighting function.
The 1159 operates at 12 volts, which is consistent with standard automotive electrical systems.
The 1159 uses a BAY15d bayonet base, a two-pin base type where the two pins are offset at different heights, a design that prevents incorrect insertion and ensures the filaments are oriented correctly within the housing.
The BAY15d base is not interchangeable with single-pin bayonet bases such as the BA15s, as the pin configuration differs in both count and positioning.
