Additional Notes

The Freightliner Coronado uses the 1157 bulb for its tail lights across all listed model years, spanning 2012-2018.
The 1157 is an ANSI-standardized bulb type, meaning its physical and electrical specifications are defined by a recognized North American standard shared across the United States and Canada.
This bulb type features a dual-filament design, which allows it to serve two separate lighting functions within a single housing, typically stop and tail functions at different brightness levels.
The 1157 operates on a 12-volt electrical system and draws 21 watts on its high-intensity filament and 5 watts on its low-intensity filament, reflecting the power demands of each respective function.
The base type is a BAY15d bayonet mount, which is an offset dual-contact configuration. The offset pin placement means the bulb can only be inserted in one rotational orientation, preventing incorrect installation.
Because the BAY15d base uses offset pins, it is not interchangeable with single-contact bayonet bases or symmetrical dual-contact bases, even when the outer housing of a socket may appear similar.
