Solid Insulation and Reliable Performance
Size: 100 Feet, Size: 100 Feet
I recently used the 12 Gauge 2 Conductor Flexible Parallel Electrical Wire for a simple switch installation on my Jeep JL's Hatch LED lights, and I’m really pleased with how it performed. The wire feels well insulated, which is important for any low voltage application. It provided a reliable connection, and the oxygen-free copper made sure I got a solid, clean signal for my setup.
The flexibility of the wire was another highlight—it was easy to work with, and I was able to route it through tight spaces without any issues. The red and black color coding made it straightforward to identify and manage the wires, ensuring I didn’t mix up the connections. This is definitely a solid option for automotive, solar panel, or LED strip lighting projects.
Overall, this wire is durable and effective for low voltage applications. It worked great for my Jeep JL, and I’m confident it would perform equally well in other vehicles or outdoor setups. If you're looking for quality low voltage wire, this one definitely gets the job done.

Highly recommend
Size: 100 Feet
I was pleasantly surprised about the quality of this wire. Very easy to use. Flexible yet truly 18 gauge copperwire. The insulation is good.
I used this wire to run some cab lights inside my fishing boat. I also ran battery charge level indicators and a phone charge. I highly recommend this wire.

Good quality wire, but thicker than expected
Size: 100 Feet
The wire itself is great quality — sturdy and well-insulated. I bought it to wire up several COB LED lights, but the individual wires and outer sheath were a bit too thick to fit into the press connectors I was using. It’ll work perfectly for other projects, just something to keep in mind if you’re using tight-fit connectors.
