Additional Notes

The Chevrolet Tiltmaster (W-Series) uses the ANSI 67 bulb for its license plate lighting across the 1992-2001 model years.
The 67 bulb operates at 12 volts and 8 watts, placing it in the low-wattage range typical of non-illumination-critical applications such as license plate lighting.
It is a single-filament bulb, meaning it serves one lighting function only, with no secondary filament for an alternate mode such as dimming or braking.
The 67 bulb uses a BA15s bayonet base, which is a single-contact bayonet mount. The "s" designation indicates a single contact pin, distinguishing it from the dual-contact BA15d base found on other bulb types.
The 67 is recognized as a lower-wattage variant of the 1156 bulb. While both share the BA15s bayonet base, the 1156 operates at a higher wattage, making the two bulbs non-interchangeable despite their physical similarities.
The ANSI 67 designation confirms the bulb meets a standardized specification recognized in both the United States and Canada, indicating consistent electrical and physical characteristics across manufacturers.
