How do i power 2 LED lights with one AA battery?

We Answered:

First, LEDs are polarity sensitive, meaning they have a + and - side. If you look at the LED from the side you'll notice a flat spot at the base of the LED. This is the negative side or the bigger metal part inside the LED is also negative.

You also must have a current limiting resister in most cases. In your case you may find it difficult to get the LED to light up from 1.5 volts as the voltage to light one is typically 3 volts.
