Re: Trying to parent the Light Source Location to my Null, but it's not working.

I'm just guessing, and I have not tested this, but maybe you need to offset the lights (assuming they're positioned correctly at the beginning of the comp) by the amount that the null has moved. Something like this:

myNull = thisComp.layer("Null Object VFX 51");
value + myNull.transform.position - myNull.transform.position.valueAtTime(0)
