When I bought my E500 this past August the only cosmetic flaw I could find was the headlights. They were yellow and hazy looking. I was planning on replacing both headlight units with new ones when I remembered the 3M headlight restoration kit. After reading up on them I purchased three kits. I used one kit to practice on my Ford Windstar's headlights, which were in really bad shape.

After:


I was very pleased with the results. I'm glad I had two more kits left. With the size of the W211 headlights and the amount of material that needed to be removed, I used one kit for each side of the vehicle.

After:


Again, I was very pleased with the results. I spent an hour on each headlight including preparation. I put two layers of masking tape around each lens in case the drill got away from me.

Looks real good,thanx for posting.I always wondered if those kits were worth purchasing , now I know.

I just did the same with mine, but didn't use the 3M kit.

I used wet/dry auto body sand paper. Wetted the lens and the paper. Started with 400 grit, then 600, 1000, 1500, then 2000. Went over each lens twice with each grit; 400 twice, then 600 twice, etc-etc, wiping the lens after each time. Followed up with a clear coat body scrub compound and then finally with "Scratch-X".

A world of difference. I'm pretty sure there is some kind of anti-reflection or anti-scratch coating on the lens and it's that coating that gets cloudy.

I bought my car new and I seem to have avoided this problem by putting the thick shielding layer with extra UV protection on them lenses. My car sits in the garage most of the time, but these thick protecting layers have actually gotten beat up by rocks and gravel more than anything. You can buy them custom cut at www.performanceproducts.com. I recommend them, especially if you just buffed and restored your lenses! I would post the link, but the site seems to be down right now.

I might be wrong, but even though you did the right thing by sanding the plastic and polishing it, they might tarnished and get cataracts quicker now that the original harder finish is gone.

When my lens covers get too beat up, I will peel them off and put new ones on.

Ya, this is a common problem on these cars. I mostly see them on W215 CL's (pre-facelift usually) and W211 E classes.

I also see a lot of W210's headlights that are horrible looking.

ss3964spd, I used the wet/dry sand paper years ago on other headlights with good results. Figured I'd give the 3M kit a try this time. There's definitely a coating on the lens. I had to sand it completely off to get a uniform surface to polish.

SAguirre, you're right. They will get "cataracts" quicker now that I sanded away the coating. I've been thinking I should apply a clear film to them sooner rather than later. Thanks for the link to www.performanceproducts.com.

Thanks for the comments.

Ya, there are a lot of those. Is it something about these oval 2-piece headlights??? I don't usually see this problem on S classes, which have a headlight that is all one piece.

Hi, I’m Djbory… This is my first post in this forum and I’m afraid it may be a little off topic, but since I’m not very familiar with this forum yet, I will post it here.
This is the thing, I own a 2003 E320… First the left turn signal stop working (just the front one) I took it to several shops, but not to MB special mechanic since in the place I live there’s not MB Certified shop…
Nobody has been able to locate the problem, and just a couple of days ago, the other side stopped working too… of course we already tried changing the light bulbs, but that’s not the problem…
The instrumental cluster display is showing that the lights are out as well… I appreciate any advice…
Djbory
P.S. I’ve been trying to buy a front license plate bracket like the one on gaazmon picture, I haven’t been able to locate one on the internet… Any leads?

Malfunction may be due to inadequate electrical contact between the turn signal bulb socket and headlamp housing. A repair kit was released for MY03 & 04, part # 2038260282 (for comparison shopping, parts.com $22.43) PM your email address and I will forward bulletin containing repair instructions.

Thank you so much, kinigstiger...I really appreciate this...I already PM you my e-mail...

That should have been posted on a separate topic so other readers can easily find them specially for the fix to the problem.

What'd you use?

NorseWagon

Had same problem.
Use wet-sanding with 1000/1500 grit and fianl polishing with Flitz.

Spent an hour on each side, but not too happy with the end result.
Should have gone with a package product like the one described above, or Maquires head-lamp restorer.
The Flitz thing was recommended by a lady in the hardware store as I was shopping for a kit..As usual I can't say no to a femme..

3M kit

4 steps:

300 then 800 then 3000 w/ water and the final step was the kind of orange spunge with a polish cleaner on it - standard kit

Had a lot of work cause Chicago's weather killed my headlights but it was worth it.....

don't be afraid about sending the surface of the lamp...

So at first i used turtle wax product and it ended up looking like ****... i had been looking for something to fix it for a while now about 6 months and even thought about getting new headlights.. But... thanks to this forum and 3m it looks amazing.. the pictures i will post dont do it justice maybe tomorrow during the day i can retake them with a normal camera. First pic is after turtle restore then the second is 3m ,, 3m take about an hour if that even, but my cordless drill kept on dyeing so i had to recharge and wait.. lol..

The 3M kit's over-the-counter, right?

Where'd you guys get it?

I'm a new owner of an 08 E350.
What is causing this hazing of the front headlights?
Is this hazing covered under the factory warranty or is it considered wear and tear?

Hubi

maybe I am wrong but 2 years in Chicago killed my headlights so maybe thats because of the winter and snow and a summer time and a high temp with high humidity........

just my guessing......

I think it usually has to do with being exposed to direct sunlight (parked outdoors for extended periods of time) for the most part. Harsh weather doesn't help either.

You did a great job cleaning up your light covers. Well done.

There's another way of performing that work: Novus plastic cleaner. I've attached a link to Novus info at the end of this note. You can get it at any motocycle store ... bikers use the stuff to clean their Lexan or acrylic windshields and goggles. I've seen it at WalMart, also. We used the same stuff (less the name brand markings) in Naval Aviation to clean aircraft canopies. I use it for my bike's windshield, my goggles, my Kubota RTV acrylic windshield, and my vehicles' headlight covers.

Squirt a dab of Novus on a clean, soft towel, spread it on the headlight cover and rub it around the cover, then polish off with a clean, dry towel. Simple as that.

I did this with my 2003 E320, I did not use a kit though. I bought a $25 buffer from Autozone, Meguire's Polish/Wax and 3M rubbing compound.

Step 1) Compound on
Step 2) Buff Out
-Wipe with cloth towel-
Step 3) Wax on
Step 4) Buff out
-Wipe with cloth towel-

Came out flawless, took me 3-4 minutes each cover.
