Chevrolet Blazer Glove Box Bulb Size

Additional Notes

• The 194 bulb is the sole glove box bulb type listed across all model years in the Chevrolet Blazer specifications provided.
• The 194 bulb is an ANSI-standardized type recognized in both the United States and Canada, meaning it conforms to a defined set of electrical and physical parameters shared across manufacturers.
• It belongs to the T10 wedge bulb family, a miniature form factor that uses a wedge-shaped base rather than a pin or bayonet mount, allowing it to be held in place by the socket walls alone.
• The bulb operates at 12 volts with a power draw of 3.78 watts, placing it in the low-wattage range typical of interior illumination applications.
• The Chevrolet Blazer (1989-2003) uses the 194 bulb for the glove box across all listed model years, indicating a consistent socket specification throughout that production span.
• Because the 194 is an ANSI-standardized wedge type, it is produced by multiple manufacturers, and aftermarket or OEM replacements carrying the same designation are generally interchangeable within compatible T10 wedge sockets.
• Substituting a bulb with a different wattage rating in a T10 socket intended for a 3.78W draw risks either insufficient illumination or excessive heat generation depending on whether the replacement draws less or more power.
