What Lighting System Does the 2015 Toyota Prius C Have?
The 2015 Toyota Prius C features an extensive lighting system with 13 bulb positions. It uses factory LED technology with integrated LED headlight modules. The Prius C has been available from 2012 to 2019, and the 2015 model falls in the mid-generation years.
Can You Put LED Bulbs in a 2015 Toyota Prius C?
Upgrading the 2015 Toyota Prius C to LED headlights is straightforward since it uses a single LED Headlights dual-filament bulb for both low and high beams. You only need one pair of LED bulbs to upgrade both functions. Look for a LED Headlights LED kit that specifically supports dual-filament operation to ensure both beams work correctly. For the fog lights, a Fog Lights LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 2015 Toyota Prius C
To remove the headlight bulb, disconnect the wiring harness, then twist the bulb counter-clockwise and pull it straight out of the housing. Older model years like the 2015 Prius C typically offer easy access to the headlight bulbs from behind the headlight assembly under the hood. Most owners can complete the swap in under 10 minutes per side. This vehicle has factory-integrated LED headlight modules. These are not user-serviceable bulbs. If your LED headlights fail, the entire headlight assembly or LED module may need to be replaced by a dealer or qualified technician. The fog lights are accessed from underneath the front bumper. You may need to remove a few plastic clips or screws from the fender liner to reach the Fog Lights fog light socket.

Factory LED headlights on the 2015 Toyota Prius C are rated for approximately 25,000 to 50,000 hours of use, which translates to roughly 10 to 15 years of normal driving. LED modules rarely burn out suddenly. Instead, they gradually dim over time or develop dead zones within the LED array. At 11 years old, the original bulbs on your Prius C are likely overdue for replacement, though LED modules may still have life left. Even if they still illuminate, reduced brightness significantly impacts nighttime safety. When one headlight burns out, replace both sides at the same time. Bulbs from the same batch age at similar rates, and mismatched brightness is distracting to oncoming drivers.
What Bulbs Are Compatible with the 2015 Toyota Prius C?
