This 2018 Subaru BRZ bulb size page helps you verify the correct bulbs by lighting position, so you can match the right replacement before you buy. The BRZ uses LED lighting in many exterior locations, but some interior and utility lamps still use standard bulb numbers, so checking each position matters.
Use this guide to confirm the bulb type for the headlight, fog light, brake light, turn signal, parking light, tail light, daytime running light, reverse light, license plate light, and cabin lights on your 2018 Subaru BRZ. It is a practical reference for owners who want to replace a single bulb or compare the full lighting setup on the car.
Fitment can vary by trim, lighting package, market, and body style, so always compare the bulb position on your car with the chart before ordering. The 2018 BRZ uses LED assemblies in many exterior spots, which means some lights may be serviced as complete units rather than with a simple replaceable bulb. If you are converting from halogen to LED or installing aftermarket lighting, check polarity, connector style, and any required resistors or adapters. The safest approach is to inspect the installed bulb or housing first, especially for shared bulb numbers and locations that can differ between regions.
The chart lists the low beam headlight as LED on the 2018 Subaru BRZ. In many cases, that means the lamp is part of an LED headlight assembly rather than a standard replaceable halogen bulb.
The high beam headlight is listed as LED for the 2018 Subaru BRZ. Because the lighting is LED-based, replacement may involve the full lamp assembly depending on the exact trim and market.
Yes. The front fog light bulb position is listed as LED on this model year.
The back up reverse light bulb is listed as 921 for the 2018 Subaru BRZ.
The license plate light bulb is listed as 168 or 917. Either number may appear depending on the exact lamp style used.
The dome light bulb is listed as DE3175 on the 2018 Subaru BRZ.
The trunk or cargo area light is listed as 168 or 917.
The interior door light bulb is listed as 168 or 917.
The front side marker light bulb is listed as 194NA, and it is marked as optional in the raw bulb list.
The chart lists the brake light, tail light, and rear turn signal positions as LED on the 2018 Subaru BRZ. Depending on the exact housing, these may be integrated LED units rather than separate service bulbs.
Yes. The daytime running light bulb position is listed as LED for the 2018 Subaru BRZ.
Because trim and lighting package differences can change fitment, and some LED-equipped positions may not use a standard removable bulb. Checking the installed bulb or housing helps confirm the exact match before purchase.
Sometimes, but not always. If the original light is a sealed LED assembly, a simple bulb swap may not be possible. For positions that do accept bulbs, aftermarket LED conversions may need proper fitment, polarity checks, and error-free operation.
