So I bought some Gen 4's on ebay about a month ago. After I put them in, I saw stress cracks on the inside of the lens on the passenger side only. Contacted the seller, sent it back and got a new one. Before I put the new one in, I took off the front bumper and made sure everything was lined up right. I've been checking the lense all this week and haven't seen any cracks until today. The passenger headlight is cracked again on the inside. Anyone have any ideas as to what's causing this?

 

i think this has been an issue with all projectors, i know some/maybe most usually swap in the OEM lenses cause the aftermarket ones are well junk

 

if i buy projectors again it will be retro fitted ones, ive only had problems with aftermarket ones

 

thats weird.
i have had mine for about 3 months no problems at all

 

I'm probably gonna get stock lenses and put them on. It's only the passenger side, not the driver side. Weird.

 

have fun entering the baking headlight part
u better hope u seal that light up properly or you will wanna throw it in a trash can

 

Thus why ebay projectors are crap..Are you running halogens? the heat may be the issue.

 

no issues with mine, you're the first i've heard with them cracking. Seems odd it has been the passenger side both times, maybe something is out of line.

 

Already baked my stockers a while ago. Not worried about the baking

I'm running the bulbs that came with them. H7's

 

subd for info

 

i actually started melting the lenses with mine when i had regualr bulbs in them. Once i put hids in i never had an issue.

 

Seems like the bulbs that come in them (halogens) run hot as do most halogen bulbs and is causing the issue. But im sure others are fine. Hit and miss.

 

RMA them again and try using HID's in the low.

Do you have to force them in the passenger side?

 

are ebay projectors really that bad?

 

Aftermarket in general is not anywhere close to OEM.

 

Yea. I had to force it a little.

 

This is the first time I've heard this happening to the Gen.4 projectors.

 

I think there's an issue with my car. The cracks aren't from the bulbs. If it was the bulbs, then the lenses would be burned instead of cracked. Would a headlight bucket issue cause this?

 

my gen 4 passanger does the same thing

 

Try running a cheap 35w hid kit in there to see if that makes a difference. Maybe the halogens are screwing it up even though they shouldn't.
Honestly, I don't understand how this can happen in the first place. It's beyond me. I still plan on buying the 4th gen projectors though since I already have an H7 hid kit.

Did you send it back & get a new one to see if it happens again?

 

I just bought a pair. I hope I dont have any problems. Can you take a picture of the cracking please.

 

I got 4th gens on mine for a week now and haven't experience anything wrong with them, other they look bit smaller than OEM's.

 

my passenger side gen 4 did the same after a few days, my replacement set arrived last night. Putting them in at the same time as i install my HID's on monday hopefully so we will see how they do

 

Let us know how that goes. Which vendor did you get them from on Ebay? If you don't mind me asking.

 

You shouldn't have to force them into place. Try adjusting the headlight bracket and seeing if that makes them go in a bit easier. Just loosen the bolts for the bracket (There are a few, you'll need to remove the light), move the bracket a bit, then tighten down.
