The max of 4 lights on at one time has changed. Superduty and some other vehicles have 6 or more on at one time. Not sure why the covers are there, but there has to be a reason. They sure as hell wouldn't put them on if they didn't have to.this is what I heard and not sure how true it is, but its something to do with restriction on how many lights they are regulated to allow to turn on at one time. I think its 4. thats why fog lights go off when brights go on. which explains why those are covered and advertised as off-road lights and do not come on the same time as fog lights. even though they are the same exact lights.
