Honda Crosstour front and rear side marker bulbs both utilize a 168 bulb size. The replacement chart covers 2012 to 2015 model years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 168 bulb is the sole bulb type specified for the Honda Crosstour across all side marker positions for the 2012-2015 model years.
The 168 bulb follows the ANSI standard recognized in both the United States and Canada, placing it within a regulated specification framework for electrical and photometric performance.
It is a miniature wedge bulb, classified under the T10 form factor, which refers to a tubular glass envelope roughly 10mm in width with a wedge-style base that seats directly into a socket without a separate metal base or pins.
The bulb operates at 12 volts, consistent with the standard electrical system voltage found in conventional passenger vehicles.
Its rated wattage of 4.9W places it in the low-power category, typical of side marker applications where illumination intensity requirements are modest compared to headlamps or brake lights.
The front and rear side marker positions on the Crosstour (2012-2015) share the same 168 bulb specification, meaning both positions draw from an identical fitment.
The T10 wedge base format is a widely used standard, and multiple bulb part numbers from various manufacturers may share this physical base type, though electrical ratings must match the 12V, 4.9W specification for correct fitment.
Because the 168 designation is an ANSI-standardized number, it corresponds to a defined set of electrical and physical parameters rather than a proprietary manufacturer classification.
