2 leads in - 2 leads out - I'd say this driver is not designed to switch off when headlights are on.
If the instructions don't show how to wire in a way to switch off the LED - then the next best bet is probably to reach back out to TRS in case the ability to do so is there but hidden in the box.
Are you able to test it - if nothing else just to verify if the LEDs you have in the headlight are still good?
