What Lighting System Does the 2018 Toyota 86 Have?
The 2018 Toyota 86 features an extensive lighting system with 13 bulb positions. It uses factory LED technology with integrated LED headlight modules. The 86 has been available from 2018 to 2019, and the 2018 model falls in the early-generation years.
Can You Put LED Bulbs in a 2018 Toyota 86?
Upgrading the 2018 Toyota 86 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 LED Fog Light LED bulb provides a clean white output that pairs well with LED headlights.
How to Replace Bulbs on a 2018 Toyota 86
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 2018 86, 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.

Factory LED headlights on the 2018 Toyota 86 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 8 years old, the original bulbs on your 86 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 2018 Toyota 86?
Using the wrong bulb size can cause improper beam patterns that reduce your visibility and blind other drivers. It can also cause overheating inside the headlight housing, potentially warping the plastic lens or reflector. Always verify the bulb number before purchasing.
