Very nice extension wires. Sheath is tough and the connections are tight. Very easy to install. I ended up to tuck in the wires instead of cutting because it was a little long for my application. Works great and had no issues. Pair the wires with my Nilight light pods. You can buy the wire but this was easier and cheaper than getting the wire and sheathing separately.
