Hello @woodymach welcome to the community! I did an experiment on this actually, yes this is possible. While it would be better to use a DC voltage, you can use AC voltage. Take a look at this post for context: Electronics Experiment: Powering LEDs With AC Voltage What you will have to do is find something called the Forward Voltage of your LEDs. Once you know that value, take the AC voltage minus the forward voltage and divide it by the current the LEDs are rated for. This will give you a proper resistor value to use in series with each LED.
