What all would i need if i wanted to make my own non pop-up headlights for my car instead of paying 1000 for it from somewhere else. I read somewhere where the Hella 90mm headlights would work well for the lights. Is there anything else that i would need or need to know to do this? Ive been wanting to do this for a while to my car b/c my headlight motors keep on going out and i think it would look cool to have non pop-up headlights.
