Can You Put LED Bulbs in a 2019 Toyota Prius AWD-e?
Upgrading the 2019 Toyota Prius AWD-e to LED headlights is straightforward since it uses a single LED Headlights dual-filament bulb for both low and high beams.

For the fog lights, a LED Fog Light LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 2019 Toyota Prius AWD-e
To remove the headlight bulb, disconnect the wiring harness, then twist the bulb counter-clockwise and pull it straight out of the housing. On the 2019 Prius AWD-e, you will likely encounter rubber dust covers behind the headlight housing. These pull off by hand or unscrew depending on the design. Allow about 15 to 20 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 LED Fog Light fog light socket.

Shop Complete LED Kit for 2019 Toyota Prius AWD-eHow Long Do 2019 Toyota Prius AWD-e Headlight Bulbs Last?
Factory LED headlights on the 2019 Toyota Prius AWD-e 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 7 years old, the original bulbs on your Prius AWD-e 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.
