How can I power 16 LED's with 2 AA batteries? What type of LED's do I need for this? Answered
I found a website that boasts a safety vest with 16 LED's powered by 2 AA batteries (see link at bottom). This confused me because I have a setup of 16 LED's in "series", but my setup requires 18v to operate. Is it the rating of my LED's? What "size" LED's do I need to get to minimize the voltage requirements?
If you're curious, I set the LED's up for my daughters Power Wheels for headlights and tail lights.
