DX,

Would have to ask what is the conditions of your headlight lens? How long have you owned the W220- possible previous owner sanded down the lens and covered with a coating that unexpectedly blocks light from fully getting through? I have struggled with low beam visibility on both a halogen S430 and a bi-xenon S500. On the S430 it was primarily a glazed over lens, on the S500- I discovered that on tight on roads with large rock formations next to the road and no should- the W220s are simply not well designed for that road type at low visibility.

 

The internal reflectors may be faded beyond usability.

 

Thanks.

Pitting, oxsidation, internal or external all possible for degradation of performance. But they are so dim, I have to suspect the function. Is there a noticeable change of luminous between drl at day or night on normal car?

Lens are not perfect but not that obvious, 2nd, why the H7 high beam works well under the similar lens?

For xenon, am I correct, there is no reflector but the lens in front of it?

 

The oem lights just aren't that good

If the h7 high beam is good then just do a hid retrofits with an after market kit

 

Thanks.

So do you think it is normal as yours is similar ?

The oem lights just aren't that good

 

These Bi Xenon lights are great when they are working right, with a few minor tweaks.

 

Agreed with tusabes and Dave2302. I've done several bi-xenon HID retrofits into Benzes now, and the difference is staggering.

I have a thread showing what bi-xenons should look like, but unfortunately the folks who administer .org domains have blocked pixhost.org for alleged "abuse". Perhaps the .org admins host a competitor. Will be sending the mods a request to edit my posts in that thread to point to the new domain.

 

Is there any schematic for the harness connector?

 

Tested on the bench, no real difference.

 

Hi,

Get a set of Depo's and read @cowboyt 's excellent threads on upgrading these.
I upgraded a set of H7 Depos to single Xenon using the MB Ballasts and OEM Wiring plus a pair of H7 HID Bulbs

Awesome, the regular H7 Full Beam is almost pointless now even on our pitch black Highland twisty roads :grin

Cheers Dave

 

If you look real close to the inside top of the low beam you will see that the reflector is black on top. The heat of the zenon bulb burns the silver coating and causes the light to be dim. It can't be fixed but you can buy a new aftermarket projector. I think it is very difficult to install. I saw this when I had my lens off.

 

Not hard to install new projector. I've done several.

 

We should all send you our lights and you do the conversions as a business.

Well, I actually wouldn't mind doing it for forum members. It's kinda fun! I still need to do Dad's car, which still has the stock Depos. It's also possible that a friend's son might buy the '03 S430, which also has the stock Depos, and if he does, I'll do the bi-xenon upgrade for him as well (he's a really good kid).

Still working on getting the pix links fixed.

 

Should not be that hard. Here are some pictures on how to dissect headlamp:

Hi,

Yes, it is very easy to take a standard MB Pre facelift Headlamp apart as per the link /\ /\ /\

However, MB Post Facelift, Depo etc have bonded on lenses and are a hell of a lot harder to get apart and re seal without ruining them :wink

Cheers Dave

 

Pix links are fixed now, thanks to Administrator.

 

The link in post #16 are not working for me. Do you have them somewhere else?

 

Are you doing this from your work computer? If so, your employer may be filtering the "Online Storage" category, which pixhost.to is in, on some Web proxies (nannies). This is the case at my employer, but the links work OK at home.

 

Post #16 Links just worked fine for me :wink
