Additional Notes

The Honda CR-Z luggage compartment uses two distinct bulb sizes across its production run: the 158 for 2013-2016 models and the 168 for 2011-2012 models.
Both the 158 and 168 are ANSI-standardized bulbs recognized in the US and Canada, meaning they conform to a defined set of electrical and physical specifications rather than being proprietary Honda parts.
Both bulb types share the T10 miniature wedge form factor, a small single-contact base that seats by friction rather than by a bayonet or screw mechanism.
Both bulbs operate on a 12-volt circuit, consistent with standard automotive electrical systems.
The 158 and 168 differ in wattage: the 158 draws 3W while the 168 draws 4.9W, meaning the 168 produces a modestly higher power draw from the vehicle's electrical system.
Although the 158 and 168 share the same T10 wedge base and voltage rating, they are not interchangeable without accounting for the wattage difference, which affects current draw and long-term socket compatibility.
The 2012-2013 model years represent the transition point where the Honda CR-Z luggage compartment bulb specification changed from the 168 to the 158, making year verification particularly important when sourcing a replacement for those vehicles.
