Lights should be wired in series or parallel?

I have two 12v LED lights I am installing. Should they be wired in series or parallel to the 12v transformer?
Since I have 2 47W LED lights, and a 120W transformer, I'm thinking it should be in parallel so current is cut across the 2 LEDs

Mc,

Lights have to be wired in parallel... so that they all receive 12 volts AC,

Thanks,

Jim R.

Thanks Jim! Makes total sense now I know the answer! And the watt output from my transformer is big enough for the 2 lights combined. I was reading that you don't need a GFCI for anything less than 15V so was not going to have one on the lights. On the pool pump & SWG I've installed a surge protector (since we live in an area with unreliable power supply) but am wondering if they should have a GFCI though?

If you had a 24 volt transformer, you could wire two identical 12 volt lights in series to use the 24 volts.

For 12 volt lights on a 12 volt supply, you use parallel.
