Honda Ridgeline Stepwell Bulb Size

Additional Notes

• The Honda Ridgeline stepwell bulb size is 194 across all listed model years from 2006 to 2024.
• The 194 bulb follows the ANSI standard recognized in both the United States and Canada, making it a widely standardized part in North American automotive applications.
• This bulb uses a T10 miniature wedge base, a compact form factor that seats by friction fit rather than by a twist-lock or bayonet mechanism.
• The 194 bulb operates at 12 volts and draws 3.78 watts, placing it in the low-wattage range typical of interior courtesy and stepwell lighting.
• Because the T10 wedge base is a common format shared across many vehicle makes and models, aftermarket and OEM-equivalent 194 bulbs are broadly available, including LED replacements built to the same base specification.
• The 2021-2022 model years are not present in the specifications, so no stepwell bulb size is attributed to those years in this data set.
• The 2015-2016 model years are similarly absent from the specifications, and no bulb size is attributed to them here.
• When substituting an LED equivalent for the 194 in stepwell applications, the replacement must share the T10 wedge base and be rated for 12-volt DC operation to maintain fitment and circuit compatibility.
