Toyota Land Cruiser Stepwell Bulb Size

Additional Notes

• The Toyota Land Cruiser stepwell position uses two distinct bulb sizes across its model year range: the 168 and the 194. Both are ANSI-standardized miniature wedge bulbs of the T10 form factor, rated at 12 volts.
• Although the 168 and 194 share the same T10 wedge base and 12-volt rating, they are not identical in power draw. The 168 operates at 4.9 watts, while the 194 operates at 3.78 watts, making them non-interchangeable without accounting for that difference.
• The 194 bulb applies to the Toyota Land Cruiser stepwell for model years 1995-2007, with the 1995 fitment noted as applicable from January 1995 onward.
• The 168 bulb applies to model years 2008-2015, with the 2015 fitment noted as applicable only through August 2015.
• The production-date qualifiers on the 1995 and 2015 entries indicate that vehicles built outside those specified windows within those calendar years may carry a different fitment, and year of manufacture alone is insufficient to confirm the correct bulb for those two model years.
• The T10 wedge base is a single-contact, wedge-style base without a separate metal cap, where the lead wires of the glass envelope itself form the electrical contacts. Both the 168 and 194 use this construction.
