W211 E200K Headlights
Im looking to give a fresh look to my 2003 E200Kompressor and thought that a good start would be the front headlights. As you will see in the pictures below the lens seems foggy/yellowy but Im not sure if that’s on the interior or the
external of the lens. Whatever the case I will give 3M products a go or DIY myself with similar products.
As far as the bulbs go, do you think that its worth replacing them? If so, whats the best configuration ij terms of xenon and halogen bulbs? I believe that right now I have xenon bulbs in main headlights and halogen bulbs for low/high beams.
Any help or opinions would be greatly appreciated.

You can also just get the headlight covers on eBay. They're around $50 and there are youtube videos on how to take it out and replace them. Somewhat of a job though as you have to heat them up to separate the glue for the new covers. But then it looks brand new because they are. The haze is on the outside so using some high grit sandpaper and sanding it down will also work temporarily as the uv will cause it to cloud up again in a few months. You can try a uv coating that might buy you a few more months.
The foggy lens cover can be replaced for new one (product from China available on ebay or aliexpress) but it will last for 2 yrs. max. You can also polish it but need to give super coating on it but mostly on the net just give a moderate result. For the projector, the lens get foggy inside and u can clean it. But if yr headlight is bi-xenon from the factory, the projector might spot burned inside and this give u a bad output. U can replace the whole projector with the new one so called EVOX-R 2.0 available on ebay or aliexpress. Search the net to get the topic on this and u will c yr answer.
Good luck n stay strong.
I would suggest that if you have time and tools that you clean them by taking out the lights and do proper cleaning. Its not difficult but is time consuming, took me the whole day from dismantling both front wheels, removing inner fender lining, removing front bumper, removing screws to take the lights out.
Once lights are out, I managed to get the lens apart without heating the glue that sticks lens and light cover together but if you have heating gun it would make the job lot easier. It's not difficult but require time and effort. You'll see the difference yourself if you do a proper job.
There was a visible scratch on my lens and using grit I manage to complete remove that scratch and was very happy with the results.
Good luck

Having read everything online I believe that in my case there's considerable dirt on the inside so maybe replacing the lens cover is the best way forward although time consuming and tricky.
