You can press "Right arrow" to go to light control, move it around with "WADSQE" and add an additional light using "P" (then click right to select it - the red diamond will indicate it is selected) and move it around. The console will show the position of the lights. Once a good position is found, you can hardcode it.
I am currently looking into adding a "sun"-like light instead of just point lights.
