    Hello, I'm trying to make my own table lamp. I'm using a 3.5 watt and 120 VAC LED bulb which is connected in series to a photoresistor, so the lamp lights when there's light reaching the photoresistor. I want to add a simple 3.5 V LED to the lamp to show when the lamp is plugged in. How can I connect this new LED to this simple circuit? Do I have to add a resistor and a diode? Are this photoresistors good for this project? Thank you for your help :)
