they have a manual knob somewhere under the hood near each headlight, on my 90 laser they are right above the headlight along the side, it will have a rubber cover on it that just pulls off, when you pull it off it shows you which way to turn the knob, just turn it untill each headlight is raised about an inch and a half
at night if you turn on your headlights they will work fine but when you turn them off the headlights will go down all the way again so you'll have to manually raise them each time, but it takes about 30 seconds and its the cheapest way to do it FREE!
I also don't think it looks as good as the 240sx sleepy eye
