loose headlight adjustment screw

Hey everybody.

So my headlights (frankensteins made up of ebay projector housings with morimoto projectors) are having issues. I'm pretty sure the vertical adjustment screw is loose. Its connected, and moves the headlight tho. I get them dialed in and aimed, then go drive around, and notice one cut off is lower. So I adjust again.. drive around.. and the same thing. It's as if the adjustment screw isnt tight enough or cant hold It in position. It turns/adjusts really easy (too easily)

Hopefully that makes sense. Lol. Any ideas on what to do?

Thanks

 

Thanks wolfpack. All of that made sense, and honestly, I did all of those steps to ensure I wouldnt have issues. This was my second time baking these and working on them. The first time was when I swapped out the projectors.. the adjustment screws were fine but the ball and socket was an issue and kept popping out. SO, the second time, I ordered another set of the ebay projectors, and swapped everything out again. This time, making sure the ball and socket were good to go. They were fine, the adjustment screws were fine and were threaded in far enough, etc. It might be that the plastic threads on the inside of the assembly are stripped like you said.

They dont really bounce or move while driving. There Is some play when I actually move the back of the bulbs.. but thats a given. I was thinking of using some silicone on the adjustment screw after I get them adjusted just so they don't move.

I think you nailed It tho with it being a combination of the weight of the projector pulling down and possible strip plastic threads. I REALLY don't want to bake them again and everything. I've done It three times and its just too much work. Lol

Any ideas to fix it without baking them?

 

Well I was thinking of just adding the silicone to the adjuster head (part with teeth) that's really all I can think of and do since the actual threads are inside the assembly ya know. Maybe wedging something in there or zip ties or something..

Yeah, I've messed with these lights way too much. Lol. They actually work and look good now, minus this issue. Lol

The only other info is this: usually when you adjust the lights, trying to turn that screw is difficult/stiff. This one is SUPER easy to turn.

I guess Ill see what I can do with silicone or even two part epoxy (for a more permanent solution)

 

Heres a few pic of the back of the housing and the adjuster. these are from the previous ones thst had the ball and socket issue. Also, while taking pics and investigating.. i played with the adjustment screw on the old housing without the screw connected to the housing inside (it freely spinning not connected) if that makes sense.. and it felt the exact same way the one on the truck feels like. it doesnt make sense tho because when I do adjust that screw, it moves the assembly, which means its obviously connected right?

 

lol no worries.

nah, they are in there sealed. they dont budge at all. i think your right Wolfpack, its probably not biting the threads. i dont think theres anything i can do unless i bake them again.

 

thanks for the offer man! i have all my stuff still tho. i just finished all this like two weeks ago too so i still have my RTV sealant. im gonna mess with them and see what i can do BEFORE baking them again.

 

Lol.. as long as its not a fat chick moose knuckle.

The more I think about it, the more i realize I can't really do anything. It's the plastic "nut" on the inside that is most likely stripped and allowing the assembly to "jump" or "pop" over the thread on the adjustment screw. I'm just going to keep adjusting them and doing the small right turn to maybe lock it in or see if it will bite. All within keeping my aiming I'm spec. :/

 

Hahahaha.. well done sir. I think that may be my only option. I'll have to look into it this weekend.
