### **Pros and Cons of buying a Harley-Davidson 91700-99 NOS Brake Light/Turn Signal Module**

#### **Pros:**

1. **Original Equipment Quality** The "NOS" (New Old Stock) designation suggests it is a genuine, unused part from Harley-Davidson s inventory, meaning it should meet the same high standards as factory-new components.

2. **Reliability** Harley-Davidson parts are known for durability, and a properly functioning brake/turn signal module ensures critical safety features work as intended.

3. **Compatibility** This specific part is designed for Harley-Davidson models from 1999 onward, ensuring a perfect fit without modification.

4. **Prevents Electrical Issues** A faulty module can cause intermittent brake lights or turn signals, leading to potential accidents. Replacing it ensures consistent operation.

5. **Resale Value** If you plan to sell your bike later, having original or NOS parts may appeal to buyers who prioritize authenticity.

6. **Warranty Coverage** If purchased from an authorized dealer or Harley-Davidson s official channels, it may come with a warranty, providing peace of mind.

#### **Cons:**

1. **Cost** NOS parts are typically more expensive than aftermarket or used alternatives, which could be a significant investment if you re on a budget.

2. **Limited Availability** Finding NOS parts may require ordering from a dealer or specialty supplier, which could involve shipping delays.

3. **Potential Overkill** If the module is functioning correctly, replacing it unnecessarily adds expense without immediate benefit.

4. **Installation Complexity** While straightforward, wiring and fitting may require mechanical skill, especially if you re not experienced with electrical components.

5. **No Significant Performance Gain** Unlike engine or suspension upgrades, replacing this module does not improve performance it only ensures proper function.

6. **Aftermarket Alternatives** High-quality aftermarket modules (e.g., from brands like *Harley-Davidson Performance Parts* or *BikeBandit*) may offer similar reliability at a lower cost.
