Review LEXUS Third Brake Light Rear High Mounted Stop Lamp Trim fits GS300 1993–1997

The **Lexus 8157030112 Third Brake Light (GS300, 1993 1997 Rear High Lamp)** is a precision-engineered automotive lighting component designed to enhance both safety and compliance for select Lexus and Toyota models from the early 1990s. This high-quality, factory-replacement brake light is specifically tailored for the **GS300 (XS70) series**, ensuring an exact fit for the rear hatch area where it serves as the third brake light, also known as the rear high lamp. Crafted with meticulous attention to detail, this component features a **clear polycarbonate lens** that provides optimal light dispersion, ensuring visibility under varying weather conditions while maintaining the vehicle s original aesthetic. The housing is constructed from durable, corrosion-resistant materials, including reinforced plastic or metal, depending on the model variant, to withstand the rigors of daily driving and environmental exposure. The bulb socket is designed to accommodate standard **amber or clear brake light bulbs**, typically a **P21W or similar low-voltage halogen type**, allowing for easy installation and replacement without the need for specialized tools. This third brake light not only meets OEM (Original Equipment Manufacturer) specifications but also adheres to strict regulatory standards, ensuring compliance with traffic safety laws that often mandate the presence of a third brake light for improved rear visibility. Whether replacing a worn-out or damaged original component or upgrading for enhanced safety, this Lexus part is a reliable choice for enthusiasts and mechanics seeking authenticity and performance. Its seamless integration into the vehicle s rear assembly ensures a clean, professional finish, preserving the GS300 s sleek, sporty silhouette while delivering the functional benefits of a properly illuminated brake system.

### **Pros and Cons of Buying a 1993-1997 Lexus GS300 (Part Number: 8157030112 Third Brake Light/Rear High Lamp)**

#### **Pros:**

1. **Compatibility and Fitment** The part number (8157030112) is designed specifically for the 1993 1997 Lexus GS300, ensuring an exact fit without modifications. This reduces the risk of installation issues or misalignment.

2. **Reliability of Lexus Components** Lexus parts, especially aftermarket or genuine OEM replacements, are generally built to high standards. A properly functioning brake light or high beam lamp improves safety and visibility.

3. **Cost-Effective Replacement** Purchasing this part individually is often cheaper than buying a full brake light assembly or waiting for a dealer to source it. This can save money compared to labor-heavy repairs.

4. **Prevents Further Damage** A failing brake light or high beam lamp can lead to more serious issues, such as wiring damage or fuse failures. Replacing it early avoids compounded problems.

5. **Legal Compliance** In many regions, malfunctioning brake lights or high beam indicators are illegal and can result in fines or traffic violations. Fixing it ensures compliance with local regulations.

6. **Ease of Installation** The part appears to be a straightforward bulb or lens assembly, which can be replaced with basic tools (no wiring harness or complex disassembly required).

#### **Cons:**

1. **Age of the Vehicle** The 1993 1997 GS300 is an older model, meaning the rest of the vehicle may require maintenance or have wear-and-tear issues unrelated to this part. Buying this part alone doesn t address broader mechanical or electrical concerns.

2. **Availability of Genuine vs. Aftermarket Parts** While the part number is specific, the quality of aftermarket replacements can vary. Cheaper alternatives might fail sooner or lack durability compared to OEM parts.

3. **Potential for Counterfeit Parts** If purchasing from an unverified seller, there s a risk of receiving a fake or low-quality replica. Always buy from reputable suppliers with return policies.

4. **Additional Costs** Beyond the part itself, you may need to factor in labor (if not DIY), wiring repairs (if the socket is damaged), or other related components (e.g., a new fuse if the circuit is faulty).

5. **Longevity Uncertainty** Even a high-quality replacement may not last indefinitely, especially if the vehicle is driven frequently or in harsh conditions. Bulbs, in particular, have finite lifespans.

6. **Electrical Issues** If the problem stems from a faulty wiring harness, corroded connections, or a blown fuse, replacing just the lamp won t solve the root cause. A diagnostic check may be necessary.

### **Conclusion:**

Buying the **Lexus GS300 (1993 1997) third brake light/rear high lamp (part #8157030112)** is a practical and cost-effective solution if your primary concern is restoring proper lighting function. The part is well-suited for the vehicle, and replacing it can enhance safety and legality. However, this purchase should be part of a broader assessment of the car s condition, especially if the vehicle has other known issues.

If you re certain the problem is isolated to the lamp and the wiring is intact, proceeding with the replacement is reasonable. For older vehicles, consider whether the overall reliability of the car justifies the repair, or if it might be more economical to explore a newer model.

### **Recommendation:**

- **Verify the exact issue** Confirm that the problem is solely with the lamp (not wiring, fuses, or switches) before purchasing.

- **Source from a trusted seller** Opt for OEM or high-quality aftermarket parts from reputable dealers (e.g., RockAuto, Amazon, or local Lexus specialists) to avoid counterfeit or low-quality replacements.

- **Inspect surrounding components** While replacing the lamp, check the wiring harness, fuse, and switch for signs of wear or failure.

- **Consider DIY installation** If comfortable with basic automotive work, replacing the lamp yourself will save labor costs.

- **Evaluate the vehicle s overall condition** If the GS300 has multiple mechanical or electrical issues, weigh the repair cost against the car s remaining useful life.

For most drivers, this is a straightforward and worthwhile repair, provided the rest of the vehicle is in decent shape. If the car is already unreliable, prioritize addressing those issues first.
