Review on 🚗 HOTSYSTEM New 3pc Car Truck Rocker Toggle LED Switch - Blue Light On-off Control: Amplify Your Vehicle's Control Panel with Style by Johnny Pigao

They do what they advertise. A few notes for some people. 1) I definitely have LEDs. Confirmed by my meter, they don't pass the conductor at all until the minimum voltage is reached. 2) An LED with no current limiting resistor conducts almost like a short circuit until it dies a smoking death. 3) These switches are best not fully "on" and fully "off" with minimal effort/effort. So you have to make sure you're actually tapping (your finger) on it when you turn it on to make sure the pins inside are fully engaged. Using the "soft-touch" switch, I measured 2.1 ohms across the switch. This means if I intended to operate the full power rating of this switch with a 12V power supply, I would be drawing over 68W from the switch alone. This could soon melt the switch and potentially damage surrounding devices. Pressing the switch a little harder when turning it on completely prevents this problem and reduces the impedance across the switch to less than 100mΩ (my meter has trouble reading well below that value). Hope that helps.
