My n/s headlamp is misted up and there's a crack in the indicator part so I am going to have to replace it. But for much the same price I can go after market and improve the look of the car at the same time. :grin:

However, I'm not over-keen on going the Projector route so I'd like to look at the crystal versions. Now there are many threads and pictures and how-tos for projector headlights fitted to R170's but precious few pictures for the clear-glass crystal headlights similar to these:

Smoked crystal headlight

Clear crystal headlight

I'd like to see pictures of either of these on the blue SLK - preferably the metallic (lighter) blue that I have before I buy. Can anyone oblige me please?

Thanks everyone

(and Jeff - apologies in advance if this should be in the General section)

I'm in agreement about the projectors. They are nicer than OEM but the crystals as you have shown are beautiful. I have no pictures but the Black ones I've seen in other posts/threads look AWESOME.

I agree both types of headlights are nicer than the projectors. But as my car isn't silver or black I think the clear lights would be better suited to my lighter blue car.

Maybe it's time for a little photoshopping.... I'll be back.

Make sure you read up on OEM Xenon headlight compatibility. Basically, if your car is OEM Xenon these aftermarket headlights will not work in you car. Trust me, I found out the hard way.

My car is fitted with normal halogens - although it does have headlight washers.

The lights are pretty good, tbh - much better than those on my 5-series, but with misting and a crack they need sorting.

So I ordered the clear crystal versions yesterday.

I also told my insurance company like a Good Boy. 0:) I started by asking a general question about mods to cars and then talked about changing the headlights. I had to laugh - the first questions she asked was how old I was and how long had I had my license. (I'm late fifties and been driving over 30 years)

I suppose before and after photos are obligatory .... :smile: Yes, of course. I just hope the weather is half-decent when I change them.

Looking forward to seeing them fitted, that's the type I would have fitted on my r170 if I'd got around to it before changing to the r171 !

Step-by-step Crystal Headlight upgrade

Well I took the front of my car apart today - looked very naked....

What we started with was this (lights off):
P3190003.jpg

And this (lights on):
P3190002.jpg

And this is what we ended up with:
P3190028.jpg
P3190033.jpg

The lights are Depo Clear Crystal lights and they come complete with the vacuum adjustments and only amber bulbs so get some new bulbs before you start.
P3190019.jpg

The main light is an H4, so you'll need to get two of these before you start and possibly the W5W / 501 sidelight bulbs too. I'll need to get some chromed indicator bulbs too when I'm next in town....

I chose to prep the lights before putting them on the car as this is likely easier than doing it afterwards.
P3190020.jpg
P3190023.jpg

So taking out the old headlights is made MUCH easier if you remove the grille first. Use an 8mm socket and remove all the self-tappers from around the grille and put them safely to one side.

Now, using the 8mm socket undo the two bolts that hold the top of the old headlight on.

Then undo the catch and slide the indicator forward, remembering to unplug the connector as the indicator comes free.

Part two...

... And gently but firmly remove the old headlight. Disconnect the power lead and the purple vacuum hose.
P3190013.jpg
P3190015.jpg

After removing the two headlights you have a rather naked looking SLK. :surprise:
P3190017.jpg

Installing the replacement headlights is a bit fiddly but basically it's the reverse of the above. First you'll find that a new 10mm bolt is installed. Fitting the lamp is easier of this is removed completely. Connect the purple vacuum hose and connect the car light connector to the headlamp harness (you'll need the adapter if you have a pre-facelift R170) then manoeuvre the headlight so it sits where it should and put the 10mm bolt in first but don't do it up tight. Fit the two 8mm bolts too and again, don't do them up tight.

The biggest issue I had was that the rubber seal wasn't well fastened to the headlamp and this needed 'persuading' into position.
P3190025.jpg

Test the headlamp fitment by clearing away your tools and closing the bonnet (or hood). You can make final adjustments to the seal and the lamps then before tightening the lamps and click-fitting the indicators (which were quite hard to seat against the rubber seal. Be warned).
P3190027.jpg

A final check that all the lights work (indicators / side lights / dipped and main beam) and then you can re-fit the grille. I must confess to gingerly closing the bonnet the first time.... :surprise:
P3190028.jpg
P3190029.jpg
P3190030.jpg

One final check that everything works then it was off to my friendly MOT station to align the lights.
P3190033.jpg
P3190037.jpg

I think that's it. Next step is a little night driving to see how they behave and then a little think about the relay wiring. One small point I noticed is that the bulb failure lamp comes on when the main beam is lit. I understand this is expected, judging by other posts, but I'm sure we can fix this with a suitable resistor. I also need to work out where to fasten the relay to stop it flapping about as I drive.

Hope this helps someone. The whole exercise took about an hour. It would have been less if I'd not taken the photos!

Cheers

Caveat Emptor!!

I should have updated this HowTo after I completed the upgrade, but posted in 'What did you do to YOUR SLK today" instead.

After fitting the crystal headlights I took them off the car and returned them to the seller.

Here's why:
  • The old (OEM) headlights run both H7 bulbs on high beam. The new Crystal lights run a single H4 so only one filament on. So only half the light.
  • Despite assurances from the seller the new headlights were NOT UK-ready. The codes on the lamps were E4 in a circle and no arrow (see photo below). From this site I found this means that they are Euro approved, but in the Netherlands, not the UK and the lack of any arrow over the E4 shows the lights are for left-hand-drive cars in Europe. Not the UK.
DEPO confirmed to me by email that they don't do these crystal lamps in RHD versions:

Dear Sir,

Thank you for your mail.

We are sorry to inform you, the item you inquired, we only have LHD version available.

If you have other demand, we kindly suggest you to contact our distributor in UK

Best Regards,

European Team
Depo Auto Parts Ind. Co., Ltd.

UK readers should therefore check the lights you buy comply with UK regulations if you decide to upgrade. Look for E11 in a circle and either a single arrow above the E11 pointing to the right or a double headed arrow pointing in both directions.

Good luck.

This may be a rookie question, but how do I know if I have xenon lights or halogen lights in my car?
All I know is that the headlight beams seem to raise up when I turn on my headlights.

probably xenon

they go through a sort of self-diagnostic aiming test when you fire up, up and down full range, and side to side if that adjustment range is fitted as well. They might not notice that if you don't have them on at start. The lamps will still do it, but if they aren't on, you won't notice. Our beemer and Alfa, which had halogen projector lights, did a similar thing as well.

If you have halogens, then the adjustment to height has to be done by you, via the thumbwheel next to the light switch.

Such a pity that they had to go back .... I've got exactly the same headlights fitted and I agree completely with what you have said, but my headlights are staying! I've fitted a new 3-bar grill and added a forth bar by adding a chrome strip which is attached to the lower front edge of the bonnet. The overall effect is stunning and the car looks unbelievably smart and modern! I keep having to glance back at it in admiration! People take their U.K. cars to Europe (I do, frequently) and they still have U.K. headlights fitted? I don't do much night driving, anyway, and my car has just passed an M.O.T. WITH those headlights. I know that I've probably just been lucky with that, I suppose. It's all worth it, to still keep that fabulous look that I've achieved. I think that it's knocked 20 years off the age of the car .... honest!

David - I did wonder about keeping them too, but as you saw from my photographs, my mechanic set them up on an MOT test bed (he's MOT-qualified too). He said that he noticed that the beam went the wrong way and strictly that would be a 'fail', if the MOT inspector was inclined to be picky, with replacement headlights needed then to pass the test.

I have also changed my grille - still with the original headlights - and agree that the front looks much better with a more modern grille. I'd have liked to have kept the lights too but I do a lot of night time driving and I live in a rural area with no street lights, so need all the light I can get. Having only one filament lit on high beam was frankly too much light to lose and this was the biggest reason for returning them, although the thought and cost of having to buy a spare headlight in addition to the crystals just to be able to swap them to pass an MOT also put me off.

Maybe I'll look again at projectors (and wire out the angel eyes!!) but that will have to wait for now.

Cheers

I'm rural, too! I'd had is in mind to open-up the Depo lights and to cut the cowls off. I'd then re-position them, with cutting, so that the angle (and hence aim) would be correct for U.K. roads. However, it simply passed the M.O.T. test. I'd even considered putting the original headlights back, just for the test. I can't see where the problem lies with the degree of illumination? These lights have sold extensively in Europe and the U.S.A. and I've not seen any adverse comment regarding the lighting? I'll just have to go out in darkness and give them a good test! Whatever happens, I'm definitely going to keep them. I just solve every problem that comes my way and they do look so modern, they're going to stay, that's for sure! Think about adding a further chrome strip above the three forming your grill. That also looks SO much better!

I did think about it. I prefer the look of the three bar grille. The four bar was just too much. I had even selected where I wanted the middle bar to touch the star - just below centre.

I know what you mean about the light from the crystal lamps. Maybe it was my H4 bulbs. I just know that when I tested I didn't get as much light as I got with the OEM lamps - particularly on the left kerb. Maybe adjusting the cowl, as you say, and better bulbs would have given me better light from the crystals.

I started with the crystal headlights. Ran them for about 4 or 5 years, then made the switch to the angel eyes.

My custom angel eye headlights was one of the best improvements to my SLK320. Receive tons of compliments about them!
I have the same headlights, but further modified them with these.

Then covered them with these.

Worlds of difference between the two; literally night and day. My halos are now as bright as the BMW daytime running halos. :grin:
