250 Poor Xenon Quality

  1. The 250 is 9 years old but only owned it for 3 months and with the dark nights I’ve noticed that the xenon headlights are very poor in output. They are very low on the road and the beam barely goes 10 metres out.
    Are they normally that bad? Or do I need to replace them? If they need replacing which D1S bulbs are the ones to go for?

    Probably just need adjusted
  3. factory fit's not the best lighting system
  4. What bulbs do you run, and has the headlights unit gone cloudy at all?
  5. Not sure on the existing bulbs that are in there. No clouding on the headlights.
  6. Are they not self levelling units? I’m guessing it’s easy to adjust?

    They are but they still have manual adjusters n the headlights

    I have Osram something in mine and they are superb but the OE bulbs wern't that bad either
  8. Cheers mate,

    I will take a look next weekend and see what’s what.
  9. On a closer inspection the headlights themselves are not cloudy but the lens in front of the bulbs are very cloudy/dirty.
    I’m guessing it’s a case of headlight out and splitting to clean?
  10. No dirt should be able to get in really, I would definitely pop and get them aligned 1st, splitting them is ball ache

  11. If your " beam barely goes 10 metres out." check you level sensor... I had the same problem in mine, it was the sensor plug out.
  12. Is it located on the light cluster?
  13. No... I think it's in the passenger side "next to the wheel", and ypu have one on the rear axle!

  14. I´ve found this video... it´s in Polish language, you can laugh a little bit, but you will understand where´s the palce to look. It´s for a Laguna, but i think it´s in the "same" place...
