Help Aiming Screw On Popup Lights Stripped!!!

[sumoboi7]

hey guys so i just installed HIDs in my popups and they were aiming like at the tops of peoples houses accross the street. i tried lowering them with the aiming screw but when i hit a bump the headlight pops back up to "blind oncomming traffic" mode. is there a way to possibly ziptie them down and have it be reliable. or would replacing the whole unit be a better choice. im not trying to spend to much money on theis front end cause im saving up for a silvia front. any help would be great thanks..
