Newly installed headlights misting up! Normal?

[Jerryong]

imo ive some friends who have experienced this before...

what they did was drill a small hole through the plastic so theres 'ventilation'... problem solved.

thanks for the advise. but I went to a lot of workshop they say cannot be fix and when its connect to headlight very noisy sound come out I suspect its aldy spoil. a lot of workshop say can only change whole sets or see anyone got this kind of spare parts. I driving Honda fit ge model 08

depends on the temperature

From my own experience

 

- Japanese car. Misting - not normal, not airtight. Commonly happen after changing/upgrading bulb/HID, eg rubber lining not align/loose etc. Or if there is a crack somewhere eg overtightened screws during installation, from flying road stone/debris.

- Mercedes brand new - headlight misting happens on day 2, both sides, lasted 2-3 days, check with C&C - told normal.

Also, the manual say so too. Fortunately, the mist never returns. So, if your car is merc ?German , can be normal i supposed.

 

Persistent presence of water vapour may cause corrosion, rust, discolouration or potentially short circuit wiring, suggest dont ignore it.

Headlight misting can never be normal especially when its "new".

 

From my experience, only certain model of really "new" headlight has water evaporate issue and that is honda accord. I'm comparing original lights and not oem or taiwan make.

With regards to the headlamps fogging issues, it seems that recently there is a rise of such complaints or feedbacks from customers, hopefully the following would be able to help you answer some of the questions from customers.

For headlamps fogging the cause is due to the cooling down of the headlamps especially after switching off during rain or after washing of vehicles. Air is drawn in and moisture from the air condenses on the headlamps lens. This is a natural process when there is a difference in temperature between the internal of the lamp and the external ambient temperature the lamps would fog. Please note that changing of new headlamps would not solve this issue.

The ventilation of the headlamps ensures that this condensation is dissipated again after a short period of operation. If customer complaints about fogging but is not present at the time of visit to the workshop then this is due to condensation and this is a natural phenomenon and does not indicate a defect or malfunction. Goodwill claims and warranty would be rejected by factory. We can’t defies the law of physics and nature.

However there might be other causes that could have resulted to this fogging like i.e. A defective headlamp, the workshop would have to check for external damage and also check for correct seating / locking of the caps. In the event that there is external damage the headlamp must be replaced.

Please note that residual fogging is possible, due to the laws of physics and this is ok. Fogging doesn’t impair the functionality or service life of the lamp unit.

Thank you and best regards

Most of them are illegal. Only a few are LTA compliant.

Any other comments? I need to know what is "normal" and "right" so I know what to do.

 

The mist is cause by water going in. Can DIY to solve the issue but damn tedious.

 

1st, you need to remove the headlight frm the car, then cleanup all the mist using cloth strips thru the hole where the bulbs goes in. Never try to dismental the headlight as the clips are made of plastics/ arcrylic, you may broke it easily.... the use silicon to seal up the headlight... check your hedlight bulb socket/ seal/ cover... is it broken, if doesnt looks good, seal it using those white plumbing tape...

 

Hope it helps...
