Recently acquired some GTI headlights and they seemed fine in the daylight. However I noticed at night with the lights on that they appear kind of misty or hazy on the outside. I tried cleaning them but this made no difference. When I touch or wet the hazy part of the lamp it momentarily disappears before returning. Almost like rubbing your finger on a steamy mirror to clear the glass only for it to almost instantly fog back up.

Has anyone come across this before?

Thanks in advance

Thanks, they don't appear to need correction, do you know how this would explain the mist which reappears almost instantly after wiping it away?

It's as the plastic ages. Halfords do a meguires headlight polishing kit for around £20 with all you need, use it with a drill to sort them. Mines starting to show signs I'll get it done soon

As others have mentioned, it sounds like the lenses are slightly oxidised causing a drop off in light quality. You have two options really either get new headlights or give them a damn good polish. Have a wee read of this helpful guide.

Hi guys sorry to bring up this post but i think i'm noticing the same thing, and ask if you did something about it.
I have a feeling the marks are from the inside of the glass, they are not visible at all in the day, only when the lights are on at night.. See here:
