Additional Notes

The 161 bulb is an ANSI-standardized type used in both the United States and Canada, operating at 12 volts and 1 watt within a T10 miniature wedge form factor.
The T10 wedge base design requires no separate socket retainer, as the bulb body itself forms the electrical and mechanical connection when inserted into the housing.
At 1 watt, the 161 is among the lowest-wattage bulbs found in automotive interior applications, consistent with its role in low-intensity illumination tasks such as ash tray lighting.
The Chevrolet Classic uses the 161 bulb for the ash tray position across the 2004-2005 model years.
Because the 161 shares the T10 wedge base with several other low-wattage miniature bulbs, substitution with physically similar types carrying different wattage ratings may affect socket integrity or circuit load compatibility.
