I would guess placement wouldn't cause them to not work unless they are getting wet or bouncing around. Check to make sure the daytime running lights aren't on. If you turn your car on there should be a green icon either on the right for drl. Or left for normal Headlights. Which one is on when you turn your car on?I installed a new HID kit and the ballast on the right side is always going out could it be the placement? Send pics of yours?
