How can i adapt this to work for 110v?

I found and made this but i would like to make it work with christmas lights so i could just plug it into an outlet and plug the lights in,

however the TIP31 transistor only works up to somewhere around 45v
is there any way to get around this?

Well, you could, if you replaced the LEDs with something like MOC3020 Optoisolators, and some cheap triacs. It has the potential to be lethal if you don't know what you are doing.

No, you need to use a similar powerpack to convert 110 volts to the correct voltage listed in the instructable.
