Buying a **1990-1991 Subaru third brake light middle lamp (part number 84701AA010BI)** involves weighing several factors, including availability, cost, compatibility, and long-term reliability. Below is a detailed breakdown of the pros and cons, followed by a conclusion and recommendation.

---

### **Pros of Buying This Part**

1. **Direct OEM Replacement**

The part is an original equipment manufacturer (OEM) component, meaning it is designed specifically for your Subaru model. This ensures a perfect fit in terms of size, shape, and electrical connections, reducing the risk of installation issues or poor performance.

2. **Reliability and Durability**

OEM parts are typically built to the same high standards as those installed in new vehicles. While the age of the part (if sourced from a used or refurbished lot) may vary, a genuine OEM lamp should still function reliably if it is in good condition. Bulbs from reputable manufacturers (e.g., Osram, Philips, or standard Subaru bulbs) are also known for longevity, especially if they are halogen or LED types.

3. **Compatibility with Aftermarket Upgrades**

If you plan to upgrade your brake lights to brighter or more modern options (e.g., LED or HID), an OEM-style socket or holder ensures that aftermarket bulbs will fit seamlessly. This flexibility is useful if you want to improve visibility without replacing the entire assembly.

4. **Ease of Installation**

The lamp is a straightforward plug-and-play component. Most Subaru models of this era have simple wiring harnesses for brake lights, and the lamp can be replaced without requiring specialized tools or extensive mechanical knowledge. This makes it a low-effort repair for DIYers.

5. **Availability of Information**

Since this is a widely recognized part number, finding installation guides, wiring diagrams, and community forums (e.g., Subaru-specific forums or YouTube tutorials) is relatively easy. This helps troubleshoot any issues that may arise during installation.

6. **Cost-Effectiveness for Basic Repairs**

While the cost of the part itself may vary, replacing a single brake light lamp is significantly cheaper than overhauling the entire brake system or replacing a faulty tail light assembly. This makes it a cost-effective solution for addressing a minor issue.

7. **Aesthetic Consistency**

Using an OEM or high-quality aftermarket lamp ensures that the appearance of your vehicle remains consistent with its original design. This is particularly important if you value the classic look of your 1990-1991 Subaru.

### **Cons of Buying This Part**

1. **Potential for Counterfeit or Low-Quality Parts**

The aftermarket for automotive parts is not always regulated, and some sellers may offer counterfeit or substandard replicas of OEM parts. These can fail prematurely, have poor light output, or even pose safety risks (e.g., loose connections or incorrect wiring). Always purchase from reputable suppliers (e.g., RockAuto, Amazon, or authorized Subaru dealers) to mitigate this risk.

2. **Age of the Part (If Purchased Used or Refurbished)**

If you buy a used or refurbished lamp, there is no guarantee of its remaining lifespan. Even if it works now, the bulb may burn out quickly, especially if it has been previously cycled on and off. New bulbs are generally a safer bet for long-term reliability.

3. **Limited Aftermarket Variety**

While OEM parts are reliable, they may not offer the latest in technology (e.g., ultra-bright LEDs or smart features). If you are looking for cutting-edge lighting solutions, you may need to explore aftermarket brands, which could involve compatibility concerns or additional wiring modifications.

4. **Wiring or Harness Issues**

Over time, the wiring harness or connectors for brake lights can degrade, leading to intermittent failures even with a new lamp. If the issue persists after replacing the lamp, you may need to inspect or replace the wiring or fuse. This adds unexpected labor or cost to the repair.

5. **Bulb Lifespan Variability**

The lifespan of brake light bulbs can vary widely depending on the brand and type. Cheaper bulbs may last only a few months, while high-quality halogen or LED bulbs can last several years. If you frequently replace bulbs, the long-term cost may outweigh the initial savings of buying a low-quality part.

6. **Potential for Misalignment or Poor Fit**

While OEM parts are designed to fit, minor misalignments can occur if the lamp housing or surrounding components are damaged. This might require additional adjustments or cleaning of the lens to ensure the light projects correctly.

7. **Environmental Factors**

Exposure to moisture, dust, or extreme temperatures can affect the performance of brake light components. If your Subaru is frequently driven in harsh conditions, the lamp may require more frequent maintenance or replacement.

### **Conclusion**

Buying the **1990-1991 Subaru third brake light middle lamp (84701AA010BI)** is a practical and often necessary repair for addressing a faulty brake light. The part is straightforward to install, ensures compatibility, and maintains the vehicle s original aesthetic. However, the quality of the part depends heavily on the source purchasing from a trusted supplier is critical to avoid counterfeit or low-quality replacements. If you prioritize reliability and ease of repair, an OEM or high-quality aftermarket bulb is the best choice. For those seeking advanced lighting solutions, exploring aftermarket options may be worth the effort, though it requires careful consideration of compatibility.

### **Recommendation**

1. **Purchase from a Reputable Source**: Buy the lamp from a well-known automotive parts retailer (e.g., RockAuto, Amazon, or an authorized Subaru dealer) to ensure you receive a genuine or high-quality aftermarket part. Avoid unknown sellers on platforms like eBay unless they have excellent reviews and return policies.

2. **Opt for a New Bulb**: If possible, purchase a new bulb rather than a used or refurbished one. New bulbs (halogen or LED) are more reliable and often come with warranties. Brands like Osram, Philips, or standard Subaru bulbs are good choices for longevity.

3. **Inspect the Wiring and Harness**: Before replacing the lamp, check the wiring harness and connectors for signs of wear, corrosion, or damage. Replace any faulty components to prevent future issues.

4. **Consider Upgrading to LED**: If you are replacing the lamp, consider upgrading to an LED brake light bulb. LEDs are more durable, brighter, and longer-lasting than traditional halogen bulbs, though they may require a compatible socket or additional wiring modifications.

5. **Follow Installation Guidelines Carefully**: Refer to your Subaru s service manual or a trusted online guide (e.g., from a Subaru forum) to ensure proper installation. Pay attention to wiring polarity and secure connections to avoid electrical issues.

6. **Test the Brake Light**: After installation, thoroughly test the brake light to confirm it functions correctly. Ensure it illuminates properly when the brake pedal is pressed and that there are no flickering or intermittent issues.

By following these steps, you can confidently replace your Subaru s third brake light middle lamp with minimal hassle and maximum reliability.
