Chevrolet Corvette Stepwell Bulb Size

Additional Notes

• The Chevrolet Corvette stepwell position uses the 194 bulb across the 1997-2013 model years, making it the dominant fitment type within these specifications.
• The 194 is classified as a T10 miniature wedge bulb under the ANSI standard applicable to both the United States and Canada. It operates at 12 volts and draws 3.78 watts.
• The wedge base design of the 194 bulb means it is retained in its socket by the tension of the base contacts rather than a separate locking mechanism, which is a common trait of T10 miniature wedge types.
• The 1995-1996 Corvette stepwell position uses the 562 bulb instead of the 194, representing a different fitment from the later model years covered in these specifications.
• The 562 is a festoon-type bulb with a 44mm length and end-cap contacts. It operates at 12 volts and draws 12 watts, which is considerably higher wattage than the 194.
• Festoon bulbs such as the 562 make contact at each end of the bulb body rather than through a wedge base, meaning the two types are physically incompatible and not interchangeable with one another.
• The wattage difference between the 562 (12W) and the 194 (3.78W) reflects a meaningful difference in power draw, and substituting one for the other without confirming socket compatibility would be inconsistent with the fitment data provided.
• Both the 194 and 562 are covered under ANSI standards for the US and Canadian markets, indicating standardized ratings and base configurations within those regions.
