### Pros and Cons of buying a WSM WES407540 Tail Light Kit for an 80-Foot Trailer (LED)

#### **Pros:**

1. **Brightness and Visibility** LED tail lights are significantly brighter than traditional incandescent bulbs, improving visibility for other drivers, especially in low-light conditions or adverse weather. This is particularly important for long trailers like an 80-foot rig, where visibility is critical for safety.

2. **Energy Efficiency** LEDs consume far less power than incandescent bulbs, which can be beneficial if your trailer s electrical system is already strained by other high-draw components. This efficiency may also extend the life of your battery or alternator.

3. **Durability and Longevity** LED bulbs have a much longer lifespan (typically 20,000 50,000 hours) compared to incandescent bulbs (which often last around 1,000 hours). This reduces the need for frequent replacements, saving time and money in the long run.

4. **Weather Resistance** Many LED tail light kits, including this one, are designed to be weatherproof (IP-rated), meaning they can withstand rain, dust, and extreme temperatures without failing. This is essential for trailers exposed to harsh conditions.

5. **Modern Aesthetic and Compliance** LED lights often have a sleeker, more modern look compared to older-style bulbs. Additionally, they meet or exceed federal and state lighting regulations for trailers, ensuring compliance without the need for additional modifications.

6. **Instant On/Off** Unlike incandescent bulbs, LEDs turn on to full brightness immediately, which is useful for quick stops or sudden braking scenarios.

7. **Wide Angle Coverage** The wide beam spread of LED tail lights ensures that the light is visible from multiple angles, improving safety for drivers behind the trailer.

8. **Compatibility with Trailer Braking Systems** Many LED kits include features like brake light sequencing or amber turn signals, which are often required for trailers with braking systems. The WES407540 appears to be designed for trailers with electric brakes, ensuring proper signaling.

#### **Cons:**

1. **Upfront Cost** LED tail light kits are generally more expensive upfront than traditional incandescent kits. While they save money in the long term, the initial investment may be a deterrent for budget-conscious buyers.

2. **Potential for Overkill** For very short trips or infrequent use, the superior brightness of LEDs may not be necessary. However, for an 80-foot trailer, this is less of an issue since visibility is paramount.

3. **Compatibility Issues** While the WES407540 is designed for 80-foot trailers, there s always a risk of wiring incompatibility or incorrect voltage requirements if the trailer s electrical system is outdated or poorly maintained. Ensure your trailer s wiring can handle the LED kit s power draw (most LEDs are low-voltage, but improper connections can cause issues).

4. **Installation Complexity** If you re not experienced with trailer wiring, installing an LED kit may require careful attention to detail. Poor installation can lead to short circuits, flickering lights, or even fire hazards. Some kits include wiring diagrams, but professional installation may be advisable if you re unsure.

5. **Potential for False Positives in Inspections** Some state or local inspectors may be skeptical of LED lights, especially if they re not familiar with them. While LEDs are legally compliant, you may need to explain their operation to inspectors to avoid unnecessary rejections.

6. **Heat Sensitivity (Less Common with LEDs)** While LEDs generate less heat than incandescent bulbs, improper installation (e.g., sealing them in an airtight housing) could cause overheating. Ensure the kit is installed according to manufacturer guidelines to avoid this.

7. **Limited Availability of Replacement Parts** If the kit fails, finding exact replacements may be harder than for generic incandescent bulbs. Stick to the manufacturer s recommended parts to avoid compatibility issues.

### **Conclusion:**

The **WSM WES407540 LED tail light kit** is an excellent choice for an **80-foot trailer**, particularly if safety, visibility, and longevity are priorities. The benefits of brightness, energy efficiency, durability, and compliance far outweigh the minor drawbacks for this application. The upfront cost is justified by the long-term savings and improved safety, especially for a long trailer where visibility is critical.

That said, if you re on a tight budget or the trailer is rarely used, a traditional incandescent kit might suffice. However, for most owners of long trailers, the **LED upgrade is highly recommended**.

### **Recommendation:**

**Buy the WSM WES407540 LED tail light kit** for your 80-foot trailer. Ensure proper installation by following the manufacturer s instructions or consulting a professional if needed. The investment will pay off in safety, reliability, and reduced maintenance over time. If you have any doubts about your trailer s electrical system, consider having it inspected before installation to avoid potential issues.
