Exactly what I needed

This was perfect for me. I had two lights bars in my rear bumper and needed to extend the harness to my fuse block. Great value

Affordable
Size: 16AWG -10FT 2Pin DT
Used them to install Morimoto 2 Banger pods on my vehicle. Casing for the wires is thick enough that will stand the weather and abrasion. I spliced them to make just one run, added braided sleeving (for looks and additional protection). The wire quality and thickness made the connection with waterproof connectors strong and durable. Saved me around 20 dollars as compared to brand name wires.
