I've recently been using an amazing 2011 cvpi vehicle model and while it has both working headlights and a spotlight, the two are integrated so that when I'm driving around with the headlights on, the spotlight is also activated. There has to be a way to modify this in the ELS XML file, or so I would reasonably believe. Many other models have the spotlight separately assigned to the ] key and as such, it can be deactivated while still using the headlights. I've looked at the structure of the ELS files that correspond with such vehicles but can't see where the modder changed it to allow for that feature. Anyways, I appreciate anyone taking the time to read this. 

Disregard the preceding post guys, I stupidly failed to realize that the "H" button was also activating and deactivating the spotlight.
