Headlights Building Up With Condensation

[John G]

Iv noticed since havin the is200 the passenger headlight is always full of condensation, any tips on how to get rid of this? anyone else got it? its driving me insane :shutit:

Dismantle the headlight (clean it up) and reseal it again- this should work.

How hard is this to do? iv removed headlights before and its been a right pig

Hi John,

I had a similar problem on a Merc Sprinter a while ago.

All I did was take the plastic cover off the back of the light (as if you were going to change the bulb) and then drove around for a few days with the headlights on to make sure the inside of the lens was totally dry.

I put the cover back on and Hey Presto...the light fogged up again! :tsktsk:

I just left the cover off from then on and the light never fogged again.

I don't know what the back of the IS headlight is like so this may, or may not be a useful post.

where would you put one though, and wouldnt it come back as soon as you removed the sachet

hang on & ill go have a search to see where i read it if i can find it - it is possible it wasnt on a 200/300 but i think it was

link- if this link works its there - or if it doesnt search headlights and look for izzys thread

[lexynik]

no sorry cant get the link to work-pcs not my strongpoint-easy search tho-it sounds as if theres foam pads in the lights which are accessible when you take the headlights off

edit - link works now

[John G]

hmmm i fail to see anywhere where u could put a silicon sachet tbh?

[lexynik]

have you tried pm,ing the members on the thread linked to see how they cured it ?

[John G]

ill have a pop at that now, cheers nik

[lexynik]

how did you get on ? failing any repair if you get as far as replacing the units i would have a look at finding a pair of later spec projector/hid units which i baelieve go in with a little bit of work and would bring it up to modern spec-lightwise - you will need to research how hard this is to do as i dont really know but the lights themselves shouldnt be too hard to source from a breakers yard

[John G]

no joy, im gona have a think, i may be some time lol

[lexynik]

hmm , sorry i cant be more help - there were loads of posts about it in search so it must be a quite common problem
