Additional Notes

The Toyota C-HR uses two distinct bulb types across its side marker positions: the 168 and the 12961, both of which belong to the T10 miniature wedge family and operate on a 12V electrical system.
The 168 bulb is an ANSI-standardized part sold across the US and Canadian markets. It carries a rated output of 4.9W and fits a standard T10 wedge base.
The 12961 is a Philips part number designation rather than an ANSI industry code. It uses a W2.1x9.5d base and is rated at 5W, placing it marginally higher in wattage than the 168.
Although both bulbs share the T10 wedge form factor, the 12961 specifies a W2.1x9.5d base, which is a defined base standard. Substituting one for the other without confirming base compatibility may result in fitment issues.
The front side marker position on the Toyota C-HR uses the 168 bulb across all listed model years, covering 2018-2020.
The rear side marker position on the C-HR uses the 168 bulb for 2018-2020 but transitions to the 12961 for 2021-2022, meaning the front and rear positions do not share the same bulb in those later years.
Because the rear side marker specification changes between the 2020 and 2021 model years, a single replacement bulb cannot serve both the front and rear positions on 2021-2022 vehicles.
