02' C240 Passenger Headlamp Restoration
This is actually my first post here on these forums, but I've been a silent lurker for the past 4 years, reading everyone elses issues and dilemnas, lol, and I really thank a lot of you guys because some of your issues really helped me solve mine haha. Anyway here is my first dilemna that I'd like to share with you all.
I own a 2002 Mercedes Benz C240, its not souped up or anything like that I'm barely making it with my $7.15 job as a sales associate, lol so everything is pretty much stock, haha. Anyway I was looking to restore my passenger headlights, I looked at various forums, does anyone know a lost cost solution that will work to restore the passenger headlights on my 2002 C240 W203 to a slightly brand new condition?. My car was hit and run last year (February 09) while parked and the insurance covered the cost of the repairs (thank goodness for full coverage). So they replaced the driver's side headlamp unit that was damaged along with the marker light and bumper total cost of the repair was over $7,000, which was all covered by the insurance company, haha. So anyway few months go by and I decided today I decided to put some aftermarket HID lights in the car, the ones that come with the error cancelor relay. And it wasn't untill after I put the brighter lights on, I noticed the nasty look of the Passenger Side headlamp housing. Its all gritty and faded, in fact it actually affects the performance of the HIDs because it produces more glare. I would take pictures but my cell phone camera sucks at night shots.
Anyway since the Passenger side headlamp is pretty old about 8 years old now, it needs to be either replaced or restored, is there anyway I can restore the headlamps without paying the hefty stealership cost of getting a new one? I did buy some polish kit made by Turtle Wax from my local AutoZone. Its a polish and a spray with a few sanding pads. I did try sanding it down a bit, its excruciatingly cold out there, so I doubt it'll work well and unfortunately it also looks as if the oxidation occured inside the lens though rather than outside from the heat of the halogen bulbs that were in there before. I also prefer the 01-04 headlamps as opposed to the 05-07 versions, they have a nicer cleaner look to it and look great with the HIDs that I installed. Thanks again!

Nice to meet you all btw!, What a large community, lol.

If you search the internet you can find new clear lenses very cheaply. You then have to unglue your existing lens with a hot air gun & glue the new one on. I've never seen a frosted (fresnel type) lens separate but they may exist.
What are your reflectors like?

Good luck
But! I'm sure that any auto-store has an applicant to put on the lens to buff away the foggy-ness/residue. Don't get it on your paint!
P.S. How do HID's look behind frosty headlights instead of clears? I'm putting my HID's in today!
Lanshift, the HIDs actually look incredible on the frosty 01-04 lens especially on the driver side lens, (the one the insurance company replaced after the hit and run). The passenger side is a bit glary and the lighting is uneven because of the oxidation and the heat stains. The lighting appears as if I have high beams on the right rather than the left because of the oxidation, lol.
Glyn, are the lenses easy to install? I probably haveto remove the entire HID kit and headlamp assembly to put them on...

i kid but i am sure someone could give you a headlight for shipping costs if yours is really that bad. :Cough: :Cough:

So basically when you analyze all of the pics, you see that the passenger side headlamps are blurry than the right now if you look at the ones with the lights on, you'll notice that the passenger side headlamps have glared, so therefore at night, the light appears excruciatingly brighter than it has to be and that can blind oncoming traffic. So I'm wondering what the solution could be, or perhaps if I can just replace the clear portion as some mentioned, its clearly not the clear one obviously when looking at the picture, I'm wondering if there are lens frames exactly like the one I have and how much it would cost to get it professionally installed, because I'm no mechanic nor body expert, lol. So I don't want to mess up anything at all, lol.

And to me that is unacceptable, I'm almost considering returning the HIDs and going back to stock, they look nice but they are just too bright its as if I have beam lights on, lol. Is there anything I can do to properly adjust the aim and angle of the HIDs or are they just not suitable for the Frosty Light housing and the 02 C240? I'm also worried that I may get ticketed by the cops for having such bright lights. I know that HIDs are naturally 3x brighter than the standard Halogens, but I know many people who have them installed and they are no where near as bright, as mine, there must be a way to adjust the positioning and the lighting angle of the bulbs.

I believe turn the screw left is to lower, and right is to raise. Not super sure, search around for "adjusting headlight height" or the like.
Sorry, have to leave!

Please have the idiots adjust it before you blind anyone else - and I would not pay them a penny to do the adjustment.

Vlad-II, I do see a decent difference in your new driver's side lense versus your older/original passenger side lense. This is typical on many cars, as after several years on the road, road debris and especially the sunlight degrade the UV coating that's on the lense. Once this coating is compromised, you'll start getting the yellowing/fading you're seeing on your passenger headlamp.
In most cases though, the damage is on the outside. Very rarely is there any damage on the inside, so I question you having to unglue your lense from your headlamp assembly. If you do, you'll probably find the inside of your lense is fine.
I actually have a car detailing side business and headlamp restoration is something that I offer to my clients. You would be amazed at the difference the products I use can do to a set of old/faded headlamps.
I do this by abrading the polycarbonate with several levels of SIS microfinishing paper. Think of microfinishing paper as exceptionally fine sandpaper. Typical sandpaper fineness is measured in the paper's grit, with most consumer sandpaper being anywhere from 20 grit (very coarse) to perhaps as high as 300 grit (very fine). The SIS microfinishing paper I use runs from as low as 120 grit to as high as 12,000 grit. 12,000 grit feels about as rough as your glass monitor (it's much finer than typical copy machine paper!).
My process does not require removal of the headlamp assembly. Depending on the level of correction needed, I'll start with a low level microfinish paper to start abrading (sanding down) the surface of the lense. At the beginning, the lense will look much foggier and opaque than when I started. I then work my way up to about a 3,600 level. Each level up makes the lense clearer and clearer. I then apply a polish to remove any scratches that haven't been removed by going up level by level to where I am now. Once I'm satisfied with the results, I'll then continue until the 12,000 level.
At this point the lense looks phenomenal and optically clear. However, if I were to leave it at this point, within 3 or 4 months, the headlamp would revert back to its' foggy state, because there is no UV protectant. My final step is to apply this UV protectant. This coats the plastic with a protective layer that's just like the coating applied at the factory when manufactured. This takes care of any other minor imperfection in the plastic and will also protect the lense from any fading for many years.
My process, as you can tell, is quite involved. And as such, I charge the clients about $90 USD for a pair of headlamps.
However...the are some products available to consumers that can do a really good job. Meguiar's has a product called PlastX, which works pretty good, but does require some decent rubbing and elbow grease. This would be my recommendation for you to try out.
To give you an example, I've attached some before, during, and after pictures of a set of headlamps I did recently for a client on her 2001 VW Cabrio. I think the results speak for themselves.

I have heard people using a mixture of mineral spirits and spar urethane (both available at you local hardware store or local Walmart paint department) in a 1 to 1 mixture. From what I've seen, it seems to work pretty well, and it has some built-in UV protection. But you need to take your time to apply it, so you don't get any streaks when it dries.
Hope this helps.
