This page helps you find the correct bulb sizes for the 2018 Toyota 86 by lighting position, so you can match the right bulb to the right socket without guesswork. Whether you are replacing a burned-out lamp or planning a full lighting refresh, checking the bulb chart by location is the easiest way to confirm fitment before you buy.
The 2018 Toyota 86 uses a mix of LED and conventional bulb types depending on the lamp position, and some items can vary by market, trim, or lighting package. Use this guide to compare the front, rear, interior, and exterior bulbs on your car and verify the exact replacement needed for each light.
Fitment can change with trim and package differences, especially on cars equipped with different lighting setups or market-specific equipment. Some positions on the 2018 Toyota 86 are listed as LED, while others use standard replaceable bulbs such as 921, 168/917, DE3175, or 194NA. If you are converting from halogen to LED aftermarket bulbs, make sure the replacement matches the socket, polarity, and physical size, and check for issues like hyperflash, beam pattern changes, or warning lights. Before ordering, it is always smart to inspect the bulb currently installed in your vehicle and compare it with the chart, since previous repairs or modifications may have changed what is actually in the car.
On this page, the 2018 Toyota 86 headlight high beam and low beam are listed as LED. Because the headlamp assembly is LED-based, you typically replace the assembly or service the specific LED component rather than swapping a standard halogen bulb.
Yes. The front fog light bulb position is listed as LED for the 2018 Toyota 86. If the fog light is not working, confirm the issue is not with the housing, wiring, or LED module itself.
The back up reverse light bulb is listed as 921. This is one of the clearest replaceable bulb positions on the car, and it is a good idea to compare the old bulb before buying a replacement.
The license plate light bulb is listed as 168 or 917. Either designation may appear depending on the bulb brand or catalog, so matching the socket and size is important when ordering replacements.
The dome light bulb is listed as DE3175. If you are upgrading to LED, make sure the replacement is designed for the same DE3175 fitment and that it works correctly with the interior lamp housing.
The trunk or cargo area light bulb is listed as 168 or 917. This is another small interior bulb that can often be replaced easily once you confirm the exact bulb type installed in your car.
The front side marker light bulb is listed as 194NA. Since side marker fitment can vary by market and trim, it is a good idea to verify the bulb currently in the vehicle before purchasing.
Yes. The brake light bulb and the center high mount stop light bulb are both listed as LED on the 2018 Toyota 86. These positions are not standard replaceable incandescent bulbs in the chart shown here.
The front turn signal light bulb and rear turn signal light bulb are both listed as LED. If you are replacing or modifying these lights, check whether your setup requires a specific LED module or a compatible aftermarket solution.
Yes. The parking light bulb, daytime running light bulb, and tail light bulb are all listed as LED. These are commonly integrated lighting functions, so replacement may involve the lamp assembly rather than a simple bulb swap.
Yes. The rear side marker light bulb is listed as LED. As with other LED positions on this car, confirm whether the issue is the bulb module, the housing, or the vehicle wiring before replacing parts.
Checking the installed bulb helps avoid ordering the wrong part, especially on a car like the 2018 Toyota 86 where trim, market, and lighting package differences can affect fitment. It is the best way to confirm whether your vehicle matches the chart exactly or has been modified previously.
