Additional Notes

The 1157 bulb is a dual-filament type operating at 12V with a 21W/5W rating and a BAY15d bayonet base. The dual-filament design allows it to serve two lighting functions within a single housing, typically combining a brighter stop light output with a dimmer running light output.
The 67 bulb is a single-filament type operating at 12V at 8W with a BA15s bayonet base. It is a lower wattage variant of the 1156 bulb family, meaning it shares the same base type as the 1156 but draws less power.
The BAY15d base of the 1157 and the BA15s base of the 67 are physically distinct. The BAY15d base features offset locating pins to accommodate its dual-filament design, while the BA15s base uses a single-contact configuration. These two base types are not interchangeable.
The Kawasaki KLF300 Bayou uses the 67 bulb for the tail light across the 1986-1999 model years, representing the longer portion of the production span covered by these specifications.
The 1157 bulb applies to the KLF300 Bayou tail light for the 2000-2004 model years, indicating a change in the lighting circuit design relative to earlier production.
Because the 1157 is a dual-filament bulb and the 67 is a single-filament bulb, substituting one for the other would result in either an incompatible base fit or incorrect electrical behavior within the tail light assembly.
