Chevrolet G-Van License Plate Bulb Size

Additional Notes

• The Chevrolet G-Van license plate position uses three distinct bulb sizes across the 1975-1995 model range: the 97, the 67, and the 194.
• The bulb 67 is the most frequently specified of the three, covering the G-Van from 1980-1994, a span of fifteen model years.
• All three bulb types carry ANSI standardization recognized in both the United States and Canada, meaning each conforms to a defined set of electrical and physical parameters.
• The 67 and 97 bulbs share the same BA15s bayonet base, a single-contact base type where a pin on the bulb aligns with a slot in the socket for a twist-lock fit. Despite this shared base, the two bulbs differ in wattage: the 67 operates at 8W while the 97 operates at 13W.
• Because the 67 and 97 share a BA15s base, physical installation into the socket is possible with either bulb, but the wattage difference means they are not electrically interchangeable without consequence to light output.
• The 97 is specified for the Chevrolet G-Van from 1975-1979, drawing 13W at 12V, which represents a higher power draw than the 67 that replaced it in subsequent model years.
• The 194 is a T10 miniature wedge bulb, a base type that uses the bulb's own glass envelope legs to wedge into the socket rather than a bayonet or screw fitting. It operates at 12V and 3.78W, making it the lowest-wattage option among the three specified bulbs.
• The 194 wedge base is physically incompatible with the BA15s bayonet sockets used by the 67 and 97, so the 1995 model year requires a different socket configuration than all prior years in the specification.
• The 67 is described as a lower wattage variant of the 1156, and the 97 is described as a variant of the 1156, both sharing its BA15s single-filament construction while differing in their rated wattage output.
