Additional Notes

The 1154 is an ANSI-standard bulb recognized in both the US and Canada, featuring a dual-filament design with a BAY15d bayonet base. The dual-filament construction allows a single bulb to serve two lighting functions, typically stop and tail, within one housing.
The 1154 is noted as an older variant of the more widely known 1157 bulb. While the two share a similar dual-filament, BAY15d bayonet configuration, they are not the same part, and substituting one for the other without confirming voltage and pin offset compatibility carries a fitment risk.
The BAY15d bayonet base uses two offset pins to ensure correct orientation during installation. This offset pin arrangement is a deliberate design feature that prevents the bulb from being seated incorrectly within the socket.
The 1154 is rated for both 6V and 12V operation, indicating it was produced to accommodate different electrical system voltages across various vehicle applications.
The Kawasaki KDX175 used the 1154 bulb for its tail light across the 1980-1982 model years, with no variation in bulb size specification across that production span.
