So, you're the proud owner (or soon-to-be owner) of a 2002 Subaru WRX - a true rally-bred beast! But let's face it, even the most legendary cars need a little TLC, and that often starts with something as simple as replacing a burned-out bulb. Figuring out which bulb goes where can feel like deciphering hieroglyphics, though. Fear not! This guide is your one-stop shop for all the 2002 WRX bulb sizes you'll ever need. We'll break it down simply, so you can get back to enjoying your WRX without the headlight headache.
Why Knowing Your Bulb Sizes Matters (More Than You Think!)
Let's be honest, swapping out a bulb isn't exactly the most glamorous part of car ownership. But it's crucial for a few key reasons:
- Safety First: Proper lighting is non-negotiable for safe driving, especially at night or in bad weather. Dim or burned-out headlights can significantly reduce visibility, putting you and others at risk.
- Avoiding Tickets: Driving with faulty lights is a surefire way to attract unwanted attention from law enforcement. Save yourself the hassle and expense by keeping your bulbs in good working order.
- Keeping That Rally Car Look Sharp: Let's not forget aesthetics! A mismatched or poorly functioning bulb can detract from the overall appearance of your WRX. Keep it looking its best.
Headlights: Illuminating the Road Ahead
Your headlights are arguably the most important lights on your car, so getting the right bulbs is essential. The 2002 WRX uses a specific type for both its low beams and high beams.
- Low Beam Headlight: The 2002 WRX utilizes a 9007/HB5 bulb for its low beams. These are dual-filament bulbs, meaning they handle both low and high beam functions.
- High Beam Headlight: As mentioned above, the 9007/HB5 bulb also takes care of the high beam function. This simplifies things, as you only need to worry about one bulb type for both.
Pro Tip: When replacing your headlight bulbs, consider upgrading to a brighter, whiter light. Many aftermarket options offer improved visibility without drawing more power. Just be sure to choose bulbs that are DOT-approved and legal for street use in your area.
Turn Signals: Signaling Your Intentions
Clear communication is key on the road, and that starts with your turn signals. The 2002 WRX uses different bulbs for the front and rear turn signals.
- Front Turn Signal: The front turn signals use a 1157A bulb. The "A" designates amber color, which is required for turn signals.
- Rear Turn Signal: Similarly, the rear turn signals also use an 1157A bulb. Again, ensure it's amber to comply with regulations.
Important Note: When installing new turn signal bulbs, make sure they're securely seated in the socket. A loose connection can cause intermittent flickering or failure.
Brake Lights: Letting Others Know You're Stopping
Brake lights are critical for preventing rear-end collisions. A quick response and bright illumination are paramount.
- Brake Lights: The 2002 WRX uses an 1157 bulb for its brake lights. While similar to the turn signal bulb, the standard 1157 is generally red.
Safety Reminder: Periodically check your brake lights to ensure they're functioning correctly. Ask a friend or family member to stand behind your car while you press the brake pedal.
Tail Lights: Being Seen from Behind
Tail lights are always on when your headlights are on, making you visible to other drivers in low-light conditions.
- Tail Lights: The tail lights also utilize an 1157 bulb. This bulb handles both the tail light and brake light function.
Troubleshooting Tip: If your tail lights are dim or not working, check the bulbs first. If the bulbs are good, inspect the wiring and connectors for any signs of damage or corrosion.
Side Marker Lights: Enhancing Visibility from the Side
Side marker lights increase your car's visibility from the sides, especially at night.
- Front Side Marker Light: The front side marker light uses a 194 bulb.
- Rear Side Marker Light: The rear side marker also uses a 194 bulb.
Upgrade Option: Consider replacing your side marker bulbs with LED versions. LEDs are brighter, longer-lasting, and consume less power.
License Plate Lights: Keeping it Legal
Illuminating your license plate is a legal requirement, so make sure these bulbs are in good working order.
- License Plate Lights: The license plate lights use a 194 bulb.
Easy Fix: Replacing license plate bulbs is usually a quick and easy task. Refer to your owner's manual for specific instructions.
Interior Lights: Illuminating the Cabin
Interior lights provide illumination inside the car, making it easier to see and find things.
- Dome Light: The dome light typically uses a DE3175 bulb.
- Map Lights: The map lights often use a 194 bulb.
Personalization Tip: Interior lights are a great way to add a personal touch to your car. Consider using colored LED bulbs to create a unique atmosphere.
Fog Lights: Cutting Through the Mist (If Equipped)
Some 2002 WRX models came equipped with fog lights, which improve visibility in foggy or low-visibility conditions.
- Fog Lights: The fog lights use an H3 bulb.
Important Note: Not all 2002 WRXs have fog lights. Check your car's specifications to confirm whether it's equipped with them.
Backup Lights: Signaling Your Reverse Intention
Backup lights illuminate the area behind your car when you're backing up, warning pedestrians and other drivers of your intentions.
- Backup Lights: The backup lights use a 1156 bulb.
Brightness Matters: Consider upgrading to brighter backup light bulbs for improved visibility when reversing at night.

- Forgetting to Disconnect the Battery: While not always necessary, disconnecting the battery before working on electrical components is a good safety precaution.
- Ignoring Wiring Issues: If your lights are still not working after replacing the bulbs, there may be an underlying wiring issue. Consult a qualified mechanic for assistance.
