Red, black, run right!
Size: 40 Feet
I got the TYUMEN 40FT 18 Gauge 2-Pin Red & Black Cable for hooking up LED strips, and it worked perfectly. The wire is sturdy, flexible, and easy to cut or connect, making installation quick and hassle-free.
The 40-foot length is generous for longer runs, and the color-coded red and black makes it easy to keep track of positive and negative connections. Great for DIY electronics, lighting projects, or any small electrical hookup.
