Additional Notes

The Chevrolet Silverado ash tray bulb specifications cover model years 1999 through 2007, with two bulb types appearing across that span: the 194 and the 161.
Both the 194 and 161 are ANSI-standard miniature wedge bulbs sharing the T10 form factor and a 12-volt operating voltage, making them physically interchangeable in terms of socket fitment.
Despite sharing the same socket type, the two bulbs differ in wattage. The 194 operates at 3.78W, while the 161 operates at 1W, meaning they produce noticeably different light output levels.
The 1999-2001 model years use the 194 bulb for the ash tray position.
The 2002 model year uses the 161 bulb without any sub-model restriction noted in the specifications.
For the 2003-2006 model years, the 161 bulb applies to the 1500 and 3500 sub-models only.
The 2007 Chevrolet Silverado returns to the 194 bulb for the ash tray position, again restricted to the 1500 and 3500 sub-models.
The sub-model restriction notation beginning in 2003 indicates that not all Silverado configurations within those years necessarily share the same ash tray bulb fitment.
