For a 2013 Subaru BRZ, the low-beam headlights use H11 bulbs, the high beams use 9005 bulbs, and if your car has fog lights, they typically use H11 bulbs as well.
In more detail, the BRZ’s headlight system is designed around standard halogen bulbs for the 2013 model year in most markets. Confirm the exact bulb sizes by checking your owner's manual, the existing bulbs, or the label in the headlight housing, as trim level and regional variations can occasionally alter the specification. If your BRZ has upgraded headlights (HID/LED) from a dealer or aftermarket, the bulb types will differ and may require ballast or adapters.
Bulb types by headlight function
The following breakdown covers the typical sizes used for the BRZ’s headlights by function. Trim and market differences can apply, so verify on your specific vehicle.
Low beam
The standard low-beam bulb for the 2013 BRZ is H11 (55W). For performance upgrades, many drivers choose H11 bulbs from brands like Philips or Osram that offer higher brightness while staying within the same size and wattage.
- Low beam: H11 (55W)
- Popular upgrade options: Philips X-tremeVision H11, Osram Night Breaker H11
Conclusion: Use H11 for the factory low beams; if upgrading, select a compatible H11 with similar wattage to avoid electrical or cooling issues.
High beam
The high-beam section uses a separate bulb, typically 9005 (HB3) in the BRZ. This is a common designation for many vehicles with separate high beams in projector or reflector housings.
- High beam: 9005 (HB3)
- Upgrade options: 9005 variants from major brands offering increased brightness
Conclusion: Replace with 9005 bulbs of your chosen brand, ensuring proper fit and installation to avoid misalignment or glare.
Fog lights
If your BRZ is equipped with fog lights, these are usually the same size as the low beams in many markets, commonly H11. Some regional variants or trims might use alternative sizes (such as H16), so confirm by inspecting the fog light housing or consulting the manual.
- Fog light (if equipped): typically H11
- Alternative (regional variations): H16 in some markets
Conclusion: For fog lights, start with H11 if your car has them; verify if your model uses a different size before purchasing replacements.
Additional considerations and tips
Before replacing bulbs, ensure the headlights are cool and the vehicle is off. Wear gloves or use a clean cloth to avoid oil on the bulb, which can shorten life. If you are upgrading to brighter bulbs, consider how wiring, reflectors, and lens cleanliness affect performance, and have the job done by a professional if you are unsure.
Summary
The typical bulb sizes for a 2013 Subaru BRZ are H11 for low beams, 9005 for high beams, and H11 for fog lights when equipped. Always verify with the owner's manual or by inspecting the current bulbs, as trim levels and regional variants can cause differences. When replacing, choose high-quality bulbs of the correct size and wattage to maintain proper beam pattern and electrical safety.
