Review: Well-Made, Meets Expectations - I am reviewing the Nilight 25 Feet 4 Way Trailer Wire Extension Cable 14 Gauge 4 Conductor 100% Pure Copper Insulated Heavy Duty Wire Weatherproof for 4 Pin Blade RV Trailer Automotive, 2 Years Warranty I selected this for our camper and had it evaluated by an electrician before installing it. The item received matched the description by the seller: “100% pure copper with 14 Gauge 4 Conductor Stranded Wire” and “featuring four color-coded wires (red, white, black and green)”. He noted that red and black are not standard vehicle wiring. Standard is white, green, brown, and yellow. Otherwise, the cable checked out with no issues. We found no nicks, gouges, or damage to any of the sheathing. In all, it appears to be a well-made product. We have purchased several Nilight electrical components for our trailer and have found their products to consistently meet expectations. This product is no different.
Review: Excellent quality, 4 conductor cable. Super thick! - NiLight's automotive grade trailer cable is of high build quality. It's a heavy duty commercial build 4 conductor weather sealed cable consisting of 14 GA copper strand wires. Overkill for wiring tail lights for a trailer! You get 25 feet in length, more than enough for most open trailers, and small camping trailers. 4 conductors is the minimum count to have functioning brake and turn signals. I'd prefer a few more conductors personally. Like at least 5 conductors. But YMMV. Other possible uses for this good cable would be for wiring runs to high power auxiliary lights. air compressors, linear amplifiers for your two-way radios. :) The cable's thick outer sheath protects the conductors very well, and this makes the cable a good candidate for other exterior applications. NiLight exceeded my expectation for this product!

### ⭐⭐⭐⭐⭐ Fantastic trailer wiring
*by J***E on March 22, 2024*

I have an older trailer that needs some improvement from damages and just wear that has occurred through time. I got this as well as some other parts to bring my tired trailer back to its former glory. Well, it is going to be better than it was when new because it has had and will have many improvements made to it. This wire is prefect for rewiring my trailer front to back. I like that the wires are all contained within one jacket making it, so I don't have to run a conduit to protect the loose wires just hanging out under there. The wire is of very good quality, and I haven't had any issues with it. I be purchasing this brand again for another trailer that is in need of wiring repair.
