Review HARLEY DAVIDSON 90138-00/90139-00 Genuine Turn Signal Mount Brackets And Hardware

The Harley-Davidson 90138-00 and 90139-00 turn signal mount brackets are precision-engineered components designed to enhance both the functionality and aesthetic appeal of Harley-Davidson motorcycles, particularly those equipped with aftermarket turn signals. These brackets are crafted from high-quality, durable materials, ensuring they can withstand the rigors of daily riding, extreme weather conditions, and the inherent vibrations associated with motorcycle operation. The 90138-00 is tailored for left-side installations, while the 90139-00 is intended for the right side, providing a symmetrical and balanced look when paired together. Both brackets feature a robust, heavy-duty construction with reinforced mounting points, allowing for secure and stable attachment to the motorcycle s frame or fairing, regardless of whether the bike is stationary or in motion.

What sets these turn signal brackets apart is their meticulous design, which prioritizes both form and function. The brackets are engineered to accommodate a wide range of aftermarket turn signal units, ensuring compatibility with popular brands and models without compromising on performance. Their sleek, angular profiles blend seamlessly with Harley-Davidson s signature styling cues, offering a clean and modern aesthetic that complements both classic and contemporary motorcycle builds. The brackets are also designed with practicality in mind, featuring easy-to-access mounting hardware that simplifies installation and maintenance, even for riders who may not have extensive mechanical experience.

Beyond their utilitarian purpose, these brackets contribute to the overall customization potential of a Harley-Davidson motorcycle. Whether integrated into a full fairing setup, a minimalist tail light cluster, or a standalone turn signal installation, the 90138-00 and 90139-00 brackets provide a sturdy foundation that elevates the bike s appearance while maintaining reliability. Their robust build ensures they can endure the demands of long rides, off-road adventures, or urban commuting, making them an essential accessory for riders looking to upgrade their motorcycle s lighting system. With their combination of strength, precision, and compatibility, these turn signal mount brackets are an ideal choice for anyone seeking to enhance both the safety and style of their Harley-Davidson.

Buying the Harley-Davidson turn signal mount brackets (part numbers 90138-00 and 90139-00) can be a practical solution for riders looking to upgrade or replace their stock turn signal mounts. Below are the key pros and cons to consider before making a purchase.

1. **Compatibility and Fit:** These brackets are designed specifically for Harley-Davidson motorcycles, ensuring a precise fit with minimal modifications required. They are engineered to align properly with the turn signal housing and mounting points, reducing the risk of misalignment or wobbling.

2. **Durability:** Harley-Davidson parts are known for their robust construction, often made from high-quality materials like steel or reinforced plastics. These brackets are built to withstand the stresses of daily riding, including vibrations and impacts from road debris.

3. **Reliability:** As OEM (Original Equipment Manufacturer) parts, they are tested and approved for use on Harley-Davidson motorcycles. This reduces the likelihood of compatibility issues or premature failure compared to aftermarket parts that may not meet the same standards.

4. **Warranty Coverage:** Purchasing from an authorized dealer or Harley-Davidson-approved supplier typically includes warranty coverage, which can provide peace of mind in case of defects or issues arising from the brackets themselves.

5. **Aesthetic Consistency:** These brackets maintain the factory look of your motorcycle, which is important for riders who prioritize the original design aesthetic. They blend seamlessly with the existing turn signal assembly, avoiding a mismatched or "bolted-on" appearance.

6. **Easy Installation:** Since they are designed to replace the stock mounts, installation is straightforward and often requires only basic tools. Harley-Davidson provides instructions or diagrams to guide riders through the process, reducing the likelihood of errors.

7. **Support for Stock Turn Signals:** These brackets are intended to work with Harley-Davidson s stock turn signals, ensuring that the functionality remains unchanged. This is particularly useful for riders who prefer not to upgrade their turn signals but still want a secure and reliable mounting solution.

1. **Cost:** As OEM parts, these brackets are typically more expensive than aftermarket alternatives. The price may be a significant factor for riders on a budget, especially if they are replacing multiple components or upgrading other parts of their bike.

2. **Limited Customization:** Since these are stock parts, they do not offer any customization options. Riders who want to adjust the angle, position, or style of their turn signals will need to look into aftermarket solutions, which may not always be as reliable or durable.

3. **Potential for Overkill:** If your current turn signal mounts are functioning adequately, upgrading to these brackets may not provide any tangible benefits beyond aesthetic consistency or peace of mind. For some riders, the cost may not justify the upgrade.

4. **Availability and Lead Times:** Depending on the region and dealer inventory, these parts may not always be in stock. Ordering online could result in longer lead times, which may be inconvenient if you need the parts urgently for a repair or upgrade.

5. **Weight:** Harley-Davidson parts, while durable, can sometimes be heavier than lighter aftermarket alternatives. While the difference may be negligible for most riders, it could be a consideration for those prioritizing weight reduction.

6. **No Additional Features:** Unlike some aftermarket brackets, these OEM parts do not come with added features such as quick-release mechanisms, adjustable mounts, or integrated lighting solutions. Riders who seek these features will need to explore other options.

7. **Potential for Misuse:** If installed incorrectly or if the motorcycle is subjected to rough handling (e.g., aggressive riding, off-roading, or frequent collisions), these brackets could fail prematurely. Proper installation and maintenance are critical to ensuring longevity.

The Harley-Davidson turn signal mount brackets (90138-00 and 90139-00) are a reliable and high-quality choice for riders who prioritize compatibility, durability, and aesthetic consistency with their motorcycle. They are ideal for those who want to replace worn or damaged stock mounts without compromising on performance or appearance. However, the higher cost and lack of customization may deter riders who are looking for budget-friendly or highly customized solutions.

If your primary goal is to ensure a secure and factory-like fit for your turn signals, these brackets are a solid recommendation. For riders who are open to aftermarket options or seeking additional features, it may be worth exploring alternatives that could offer better value or functionality.
