Review on 🔴 High-Performance Red LED Toggle Switch with Aircraft Style Cover - Perfect for LED Light Bar, Fog Lamps, Daytime Running Light, and More! by Nate Ducey

I used this as the second auxiliary power input. When the switch is off. And the power comes from another source. The light is still on. Let me know the line is hot. When there is no glow. And I need it to be activated. I can use this switch to add power whether another source is powering it or not. Strange use case. But for me it worked perfectly.
