How would I modify this circuit for battery powered string lights?

How would I modify this instructable to use a string of lights that runs on 2 AA batteries?

I figured it would be a matter of using a different solid state relay but I'm not sure. If it IS just a matter of switching ssr's, any idea what one to use?

Thanks in advance

You should be fine with the relay used in the original, or even one with a lower voltage rating, as the one in the video is good for 24V, and the pair of AAs will only output 4V.
