4 Reasons to Buy a Lighted Extension Cord
The power drain is negligible The LED or neon light draws about 0.01 watts—less than most phone chargers waste when idle.
The heat is not a problem The light stays cold to the touch even after hours of use. I’ve tested several with my fingers.
The light improves safety You can tell at a glance if the cord is live. That’s useful in a garage, basement, or with holiday lights.
The light does not increase fire risk The only real fire risk from an extension cord is overloading or damage. The built-in light does not change that.
