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

I have two garden solar LED light systems. Each one is powered by one AA battery. I plan on using the bulbs for an RC car project, but i seem to be having problems. Im not a tech guy or nothin so im kinda lost when it comes to this stuff. Here is my problem. I want both bulbs to run off of the same battery, without one loosing power or getting dim. So far what ive done is just , taken off the curcuit board and attached the two wires from one LED to the other LED’s connections. I know there is something im missing, just dont know what. I really want to avoid using another battery as it adds weight to my rc car. Any tips or suggestions would be greatly appreciated.

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.
