led potentiometers

Dear All I've recently disassembled an LED lamp because the touch-buttons for it stopped working. I now intend to replace the electronics inside with physical controls, more specifically a potentiometer (with an end-switch if possible). This would allow me to set a dimming level permanently by...

I am using multiple LEDs (20mA 3-12V) in parallel to indicate active circuits in a car. They are too bright at night, so I put a 250K potentiometer to their collective ground. At less resistance, some LEDs are brighter than others. At greater resistance, the brightest LEDs become the dimmest. 1...
