If you're searching for how to replace the tail light on a 2013 Toyota Corolla, you're not alone—thousands of owners face cracked lenses, dim bulbs, or moisture buildup each year. The good news: replacement is straightforward, cost-effective, and can be done at home with basic tools. This comprehensive guide covers everything from identifying the correct tail light assembly (OEM part number 81550-02751), choosing between OEM and aftermarket options, step-by-step installation, common problems like water intrusion, and how to avoid compatibility mistakes when purchasing online. Whether you’re dealing with a broken lens, flickering brake lights, or upgrading to LED, this article gives you the knowledge to make informed decisions and complete the job safely and correctly.
Understanding the 2013 Toyota Corolla Tail Light System
The 2013 Toyota Corolla uses a dual-lens rear lighting system that integrates multiple functions into one housing unit. Each tail light assembly includes separate bulbs for:
- Tail/running lights (red illumination when headlights are on)
- Brake lights (brighter red when brake pedal is pressed)
- Turn signals (amber flashing)
- Reverse lights (white when in reverse gear)
🔧 Unlike some newer models, the 2013 Corolla does not use full LED taillights as standard equipment across all trims. Most base models (L, LE) come with halogen bulbs, while higher-end versions may have partial LED elements. However, many owners choose to upgrade to aftermarket LED assemblies for improved visibility and aesthetics.
🛒 The factory tail light assembly is identified by Toyota part number 81550-02751 (driver side) and 81561-02751 (passenger side). These are interchangeable between left and right due to mirrored design. Knowing this number helps ensure compatibility when shopping online or at auto parts stores.
Common Signs Your 2013 Corolla Tail Light Needs Replacement
Before buying new parts, confirm whether the issue lies with the bulb, socket, wiring, or the entire housing. Common symptoms include:
- One or more lights not illuminating (e.g., brake light works but tail light doesn’t)
- Foggy or cloudy lens due to moisture ingress
- Cracks or impact damage from road debris
- Intermittent operation (flickering)
- Burnt-out filament visible through the lens
❗ A frequently overlooked problem is corrosion inside the electrical connector. Over time, water can seep into the harness, causing poor contact even if the bulb is functional. Inspect the plug behind the light assembly for greenish residue or bent pins.
| Function | Bulb Type (2013 Corolla) | Typical Lifespan | Wattage |
|---|---|---|---|
| Tail / Running Light | 1157 (dual-filament) | 4,000–5,000 hours | 27W / 8W |
| Brake Light | 1157 (shared filament) | 4,000–5,000 hours | 27W |
| Turn Signal | 3157NA (amber) | 3,000–4,000 hours | 27W |
| Reverse Light | 921 (clear) | 5,000+ hours | 21W |
🔧 Pro Tip: Always test bulbs before replacing the entire assembly. You can remove the bulb and check continuity with a multimeter or swap it with the opposite side to verify function.
OEM vs Aftermarket Tail Lights: What’s Best for Your 2013 Corolla?
When replacing a damaged or outdated tail light, you’ll face a key decision: stick with genuine Toyota parts or go with an aftermarket alternative. Here's a detailed comparison:
Genuine OEM Tail Light Assemblies (Factory Original)
🏭 Toyota OEM units are manufactured to exact specifications and carry the same quality control standards as the original equipment. Advantages include:
- Precise fitment—no gaps or alignment issues
- Weather-sealed design prevents moisture entry
- Color-matched lenses for consistent appearance
- Backed by dealer warranty (if purchased through dealership)
However, OEM parts are typically more expensive—often $100–$160 per unit—and may require longer shipping times unless available locally.
Aftermarket Tail Light Assemblies
👥 Third-party manufacturers offer alternatives ranging from budget replacements to premium LED upgrades. Benefits include:
- Lower price point ($20–$80 typical range)
- Availability of LED, sequential, or smoked lens designs
- Faster delivery from online retailers
⚠️ But there are risks: Some low-cost units suffer from poor sealing, leading to fogging; others may have slightly different mounting tabs or lens tints that affect legality or aesthetics. Always look for DOT/SAE certification labels and read verified buyer reviews focusing on durability and waterproofing.
✅ Recommendation: For daily drivers in wet climates, OEM is safer. For cosmetic upgrades or budget-conscious repairs, choose reputable aftermarket brands with clear return policies.
Step-by-Step: How to Replace a 2013 Toyota Corolla Tail Light Assembly
⏱️ Time Required: ~20–30 minutes per side
🛠 Tools Needed: Phillips screwdriver, 10mm socket wrench (optional), gloves
- Disconnect the Battery: For safety, disconnect the negative terminal to prevent short circuits during work.
- Open the Trunk: Gain access to the area behind the tail light. Remove any carpeted trim panel using a plastic pry tool.
- Unplug the Wiring Harness: Locate the main electrical connector at the back of the assembly. Press the release tab and gently pull it free.
- Remove Mounting Nuts: There are three 10mm nuts securing the tail light to the body. Use a socket or wrench to remove them.
- Pull Out the Assembly: Gently wiggle the housing outward. It may be sealed with weatherstripping—apply steady pressure to avoid cracking.
- Install New Unit: Align the new tail light with the mounting holes and push until it seats fully.
- Reattach Nuts and Reconnect Wiring: Tighten the nuts securely but do not over-torque. Plug in the harness until it clicks.
- Test All Functions: Reconnect the battery and have someone assist in testing tail lights, brake lights, turn signals, and reverse lights.
🧼 Pro Tip: Apply a thin bead of silicone sealant around the inner edge of the new housing before installation to enhance moisture resistance—just avoid blocking drainage holes.
Can You Replace Just the Bulb Instead of the Whole Assembly?
Yes—in many cases, you don’t need to replace the entire housing. If only one function (like the brake light) fails, it’s likely a bulb issue. To replace a bulb:
- Access the back of the tail light through the trunk liner.
- Twist the bulb socket counterclockwise to remove it.
- Pull out the old bulb and insert the new one (avoid touching halogen bulbs with bare fingers).
- Reinstall the socket and test.
⚡ Important: The 1157 and 3157 bulbs are dual-filament. If one filament burns out, the other may still work—this explains why your running light might be out but brake light remains functional.
Upgrading to LED: Is It Worth It for a 2013 Corolla?
✨ Many owners upgrade their 2013 Corolla tail lights to LED for several reasons:
- Improved brightness and faster response time (safer braking alerts)
- Longer lifespan (up to 50,000 hours vs. 5,000 for halogen)
- Modern, sleek appearance
- Lower power draw on the electrical system
However, direct LED bulb swaps in halogen housings can cause glare or improper beam pattern. For best results, install a complete LED tail light assembly designed for the 2013 Corolla. These are engineered to diffuse light properly and maintain legal compliance.
🌐 Note: Some states require that modified lighting meets FMVSS 108 standards. Check local regulations before installing non-OEM LED units, especially those with animated sequences or extreme tinting.
Where to Buy Compatible Tail Lights for a 2013 Toyota Corolla
🚚 When purchasing replacement parts, consider these factors:
- Fitment Accuracy: Confirm the listing specifies “2013” model year. Earlier (2009–2012) or later (2014+) Corollas have different shapes.
- Seller Reputation: Look for sellers with high feedback scores and real customer photos.
- Return Policy: Choose suppliers offering returns within 30 days in case of defects or fitment issues.
- Shipping Cost: Factor in delivery fees, especially for heavy glass-containing units.
🔍 Avoid listings labeled “fits multiple years” without specific confirmation for 2013. While minor variations exist between sedan and hatchback models, the 2013 Corolla sedan (E170 chassis) uses a unique rear lamp design not shared with prior generations.
