Toyota C-HR high beam and low beam headlight bulbs use 9005 or 9012 size bulbs for optimal illumination. The replacement chart covers 2018 through 2020 production 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 9012 bulb type appears across both the high beam and low beam positions for the 2018-2019 model years, making it the most consistently specified bulb in these listings.
The 9012 is an HIR2 (Halogen Infrared Reflecting) bulb, which uses a reflective coating on the capsule to redirect infrared energy back onto the filament, improving luminous efficiency compared to standard halogen designs while operating within a similar wattage range.
The 9005 bulb is specified for both the high beam and low beam positions on the 2020 Toyota C-HR, but only under the condition that the vehicle is equipped with Halogen Capsule Headlamps.
The 9005 is a single-filament halogen bulb rated at 65 watts, commonly used in North American vehicle lighting applications and widely available across multiple manufacturers.
The 9012 and 9005 bulbs are not interchangeable despite sharing a similar physical base family. The 9012 has a different locking tab configuration and a higher luminous output relative to its wattage, which means substituting one for the other without an adapter is not supported by these specifications.
The shift from 9012 in 2018-2019 to 9005 in 2020 reflects a change in headlamp system type, as the 2020 specification is explicitly conditional on the presence of Halogen Capsule Headlamps, indicating that not all 2020 trim configurations use the same bulb.
Both the high beam and low beam positions share identical bulb specifications within each model year, meaning a single bulb type serves dual functions in the headlamp assembly for each respective year.
