Projector lens bubbles?!

[NateDG]

So I opened my headlights again to swap out the MD2S 2.0s in the low beam for MD2S 3.0s (tremendous improvement) but after I baked them back closed and installed them, I noticed the PS lens had all kinds of bubbles and/or streaks of some kind. It didn't look like this out of the box. What could have possibly happened? Has anyone seen this condition before and/or know how to correct it? Doesnt seem to mess with the output any, but it's definitely pinging my quasi-OCD something awful. Thanks in advance.

That looks like dust on the lens and not anything bad. The lens on my projectors is made of glass so it wouldn't bake and bubble like plastic would. You can only try to get in with a rag and maybe a screwdriver with the rag taped to it tightly to go through the back side of the projector to clean it out but it looks like yours is on both sides of the glass. I wouldn't worry about it imo.

Yeah it is dust. I had that on mine too, annoying because you try your best to keep it clean and it somehow still gets in there and on stuff almost right away too

So what are the 2.0 worth to ya? Got to be better than the halogen projector I got curently

What about the baking would cause this, and only on the one side?

I hadn't really thought about what I was gonna do with them. I guess shoot me an offer and we'll see what we can make happen.

It didn't... At some point when you had the headlight open, there was some dust that settled in there. You just didn't notice until after you sealed them back up.

I dont like to touch the projector lens, but have used a microfiber towel to remove a finger print. Anytime I had the lens off of a headlight/fog light, I used compressed air to blow out any dust/debris before sealing the lens back on.

That's why I don't understand this because not only did I clean the lens with IPA before reassembling everything, I used a whole can of duster between the 2 assemblies.

If you've ever shined your
Phone camera inside your house, you'll literally see billions of dust particles floating around. Completely invisible to the eye, but dangerous to the painters and retrofitters. Unless one has some sort of sealed paint booth that sucks the air in the room outside 24/7 you'll always have that chance of getting dust particles on everything, including into your lungs

And I totally dig what you're saying but if ya see the pics in the OP, that's a pretty huge difference between two lights assembled within minutes of each other and cleaned/prepped in the exact same manner.

I know, but you can be surprised. One had a bit of static buildup the other didn't, or a small dust cloud wafted by at the wrong time, something.

It isn't bubbles in the lens caused by baking because you'd melt the plastic housing long before doing any heat damage to the glass lens.

It's in the driver's side too, just not as bad. No matter how you cut it, that's dust on the inside of the lens. Can only be properly remedied by a tear down. Honestly I'd probably leave it, who's gonna look that close besides you.

 

[NateDG]

Contrary to the title of the post, I don't think it's bubbles in the glass but I didn't know if there was some kinda coating applied to the surfaces of the lens that reacted poorly to something. I'll tear into it tomorrow (hopefully). And yes, me noticing it is too much. I'm far too perfectionist to allow something like this to exist hah.

 

[07TrailyLS]

Out of curiosity. Wouldn't the heat of the projector bake that dust to nothingness?

dust and/or WATER SPOTS, I had a set of projectors that I bought as part of a full kit where the low beam projectors where shot, but I was buying them for the other parts of the kit so I could use a different projector setup on my Firebird and it had spots like that on the inside of the lenses, it cleans off easily enough, it's just a pain in the ass to get to
