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.

Excellent lights
Color: Yellow & Spot Flood Combo
These are great lights. Put them on my side by side and they are very bright at night. They also work great in dusty environments. I would leave them on all day long riding the trails so people could see me coming in the woods easier.
