The **J.W. Speaker MN/7391 JW 8700 EVO Dual Burn Headlight** is a premium, high-performance lighting solution meticulously engineered to elevate the presence and visibility of your 2018 Harley-Davidson FLHCS "Broadway" motorcycle. Designed with cutting-edge technology and a bold aesthetic, this headlight system delivers an unparalleled combination of brightness, precision, and durability, ensuring both safety and style on every ride. At its core, the JW 8700 EVO features a **dual-burn LED architecture**, integrating a high-output **100-watt main beam** with a **50-watt auxiliary beam**, creating a dynamic, adaptive lighting profile that seamlessly transitions between low and high beams with a single flick of a switch. The main beam projects a **wide, even spread of illumination** up to **1,000 feet ahead**, cutting through fog, rain, and nighttime darkness with clarity, while the auxiliary beam enhances peripheral visibility and accentuates the motorcycle s aggressive stance. Crafted from **high-grade aluminum and reinforced polycarbonate**, the housing is both lightweight and robust, designed to withstand the rigors of off-road adventures and daily commutes alike. The **hydrophobic lens coating** ensures water beads instantly, preventing glare and maintaining optimal light output even in wet conditions, while the **low-profile, aerodynamic design** integrates seamlessly with the FLHCS s sleek bodywork, preserving its iconic silhouette without compromising functionality. Beyond its performance, the JW 8700 EVO is a statement piece, boasting a **sleek, angular housing** with **precision-machined details** that reflect the Harley-Davidson s muscular heritage. The **customizable mounting bracket** allows for precise alignment, ensuring the headlight s beam pattern is optimized for your riding style, whether you re cruising down a city street or tackling a winding highway. With its **long lifespan (50,000 hours)** and **low power consumption**, this headlight not only outshines stock options but also reduces energy drain on your bike s electrical system. Whether you re a rider who demands cutting-edge technology or a purist who appreciates the marriage of form and function, the JW 8700 EVO Dual Burn Headlight transforms your FLHCS into a head-turning machine, blending Harley s legendary spirit with the future of motorcycle lighting.

### **Pros and Cons of buying a J.W. Speaker MN/7391 JW 8700 Evo Dual Burn Headlight for a 2018 Harley-Davidson FLHCS (Bj)**

1. **Enhanced Visibility** The dual-burn headlight provides significantly brighter illumination compared to stock OEM units, improving nighttime visibility and safety. The high-performance LEDs offer a wider and more focused beam pattern, reducing glare for oncoming traffic while still maintaining strong forward lighting.

2. **Durability and Build Quality** J.W. Speaker is known for producing high-quality aftermarket lighting solutions designed to withstand harsh conditions, including vibration, heat, and moisture. The housing is typically made from durable materials like polycarbonate or aluminum, ensuring longevity.

3. **Compatibility** The MN/7391 model is specifically designed for Harley-Davidson applications, including the FLHCS (Bj), ensuring a proper fit without modification. It integrates well with the bike s electrical system, though verification of wiring compatibility is recommended.

4. **Aesthetic Appeal** The sleek, modern design of the 8700 Evo series enhances the bike s appearance, giving it a more aggressive and contemporary look. The dual-burn configuration adds a sportier aesthetic compared to single-headlight setups.

5. **Performance Features** The headlight includes advanced optics that reduce light scatter, improving clarity and reducing the need for frequent adjustments. Some models also feature adaptive lighting modes or smart controls, though this depends on the specific variant.

6. **Warranty and Support** J.W. Speaker offers warranties on their products, and their customer service is generally reliable for troubleshooting or replacements if issues arise. Many dealers also provide installation services.

7. **Positive User Feedback** Many Harley riders report noticeable improvements in visibility and confidence when riding at night after installing J.W. Speaker headlights. Reviews often highlight the brightness and durability of the product.

---

1. **Cost** The J.W. Speaker 8700 Evo is a premium product, and the price point is significantly higher than stock headlights or budget aftermarket alternatives. Installation by a professional may also add to the expense.

2. **Installation Complexity** While the unit is designed for easy installation, replacing the stock headlight may require some mechanical skill, especially if wiring or mounting brackets need adjustment. Professional installation is recommended to avoid electrical issues.

3. **Potential for Overhead Clearance Issues** Some riders report that the larger size of dual-burn headlights may occasionally scrape low-hanging obstacles (e.g., parking garage ceilings or low branches) if not properly secured or if the bike is heavily loaded.

4. **Electrical Compatibility Concerns** Although the unit is Harley-compatible, there is a slight risk of electrical incompatibility if the bike s wiring harness or fuse box is not properly accounted for. Always verify voltage and amperage requirements before installation.

5. **Weight** Dual-burn headlights are heavier than single units, which could slightly affect the bike s balance or handling, though the impact is typically negligible for most riders.

6. **Blind Spots or Adaptation Period** Some riders experience an initial adjustment period when switching from stock lighting to the brighter J.W. Speaker headlights. Oncoming drivers may also be momentarily blinded, though this is less common with the optimized beam pattern.

7. **Limited Customization** Unlike some aftermarket options, the 8700 Evo series offers fewer customization choices (e.g., color, beam pattern adjustments) compared to modular LED kits. The design is fixed to the Harley-specific build.

The J.W. Speaker MN/7391 JW 8700 Evo Dual Burn Headlight is a high-quality upgrade for the 2018 Harley-Davidson FLHCS (Bj), offering superior visibility, durability, and a modern aesthetic. While the cost and installation considerations are notable drawbacks, the performance benefits particularly for nighttime riding outweigh these for most serious riders. The product s reputation for reliability and compatibility with Harley-Davidson motorcycles further strengthens its case as a worthwhile investment for those prioritizing safety and lighting performance.

If budget and installation logistics are not prohibitive, the J.W. Speaker 8700 Evo is an excellent choice for riders who want to enhance their FLHCS s lighting without compromising on quality. For those concerned about cost, it may be worth comparing it to other premium brands like HID or LED manufacturer options (e.g., Sylvania, Philips, or other Harley-specific dual-burn units) to ensure the best value. Always opt for professional installation to guarantee proper wiring and functionality. Ultimately, the upgrade is justified for riders who frequently travel at night or prioritize visibility and a premium look.
