Additional Notes

The Peterbilt 362 uses the 97 bulb for the dome light across all specified model years, spanning 1986-1997, under the condition that the vehicle is equipped with 2 rectangular headlamps.
The 97 bulb is an ANSI-standardized type recognized in both the United States and Canada, operating at 12 volts and 13 watts.
A BA15s bayonet base is the mounting interface for the 97 bulb. The BA15s designation indicates a single-contact bayonet fitting with a 15mm base width, which requires a socket designed specifically for that base type.
The 97 bulb is a single-filament type, meaning it serves only one lighting function rather than switching between two brightness levels as a dual-filament bulb would.
The 97 is a variant of the 1156 bulb. While both share the BA15s base and single-filament construction, the 97 operates at a lower wattage than the 1156, which is rated at approximately 26.9 watts. Substituting one for the other may result in incorrect light output or electrical load.
