This page helps you verify bulb sizes for the 2021 Toyota 86 by lighting position, so you can match the correct bulb to the correct lamp before ordering. The 86 uses LED lighting for many exterior functions, but a few serviceable bulbs still use standard sizes, which makes position-specific checking important.
Because trim, market, and lighting package can vary, the bulb list for the 2021 Toyota 86 is best used as a fitment guide rather than a one-size-fits-all rule. Use the location on the vehicle, not just the bulb type, to confirm what you need for headlights, tail lamps, interior lights, and license plate lighting.
For the best fit, compare your current bulb and housing before buying, especially if your 2021 Toyota 86 has a different trim, a special package, or a market-specific lighting setup. Some positions are LED from the factory, while others may use replaceable bulbs such as 921, 168/917, DE3175, or 194NA, and aftermarket LED conversions can change the required fitment or trigger compatibility issues. If you are replacing a failed bulb, check the installed bulb number and connector style first, then confirm whether your car uses halogen or LED equipment in that location before ordering.
The 2021 Toyota 86 uses LED lighting for both the high beam and low beam headlight functions on this page. Since the headlight assembly is LED, the service approach may differ from a traditional replaceable halogen bulb setup.
The front fog lights are listed as LED on the 2021 Toyota 86. In many cases, that means the light source is integrated into the lamp assembly rather than using a standard plug-in bulb.
The back up reverse light bulb is listed as 921. Always confirm the bulb in your vehicle before purchase, since trim or market differences can affect the exact setup.
The license plate light bulb is listed as 168 or 917. Either size may appear depending on the source listing and application, so checking the installed bulb is a good idea before ordering.
The dome light bulb is listed as DE3175 for the 2021 Toyota 86. This is the interior overhead light bulb size shown for this page.
The trunk or cargo area light uses 168 or 917. If your car has been modified or fitted with an aftermarket lamp, verify the bulb in the socket before replacing it.
Yes. The brake light bulb, tail light bulb, and center high mount stop light are listed as LED on this page. These are typically factory LED functions rather than standard replaceable bulbs.
The front side marker light bulb is listed as 194NA, and it is marked optional in the raw fitment notes. That means fitment may vary by market or lighting package.
The rear turn signal light is listed as LED. Because it is LED, the lamp may not use a conventional replaceable bulb the way older vehicles do.
Yes, but fitment and compatibility matter. Some positions are already LED from the factory, while others use standard bulbs such as 921, 168/917, DE3175, or 194NA, and aftermarket LED conversions may require the correct polarity, resistor, or CAN-bus compatible design.
Trim, package, body style, and market can all affect the lighting setup. That is why the same model year may show different bulb arrangements in certain positions, especially for optional or package-dependent lights.
Check the bulb location, the installed bulb number, and whether the lamp is LED or a replaceable bulb. If possible, remove the old bulb and compare it to the replacement before purchase to avoid fitment mistakes.
