Hi

I had the same problem. Getting rid of the moisture isnt hard, have a scan on youtube and they show you how to do it. I took the light unit out of the car. This is not as scary as you may think and you can do it. I have done it ten times now and can do it with my eyes closed. Get light out, take out bulbs. Plug the light bulb holes with cloth. leave the cornering light hole open and blast air down the hole with the hairdryer. The moisture will disappear. Then get some clear mastic and reseal the clear lense to the plastic to stop moisture getting back in. Whilst you have lights off unscrew the silver ballast box thats on the light. Give it a shake as it may contain water that has seeped in, consider changing if you want. Put it all back together.

Now I did all that and afterwards had a big problem with one of my dipped and main beam. But that probably has something to do with the new ballast I put on (to be confirmed). Depending on what type of light you have and the cost, a new set of freshly bought lights do look really good, just a thought.

Regards

Hi, hoping someone still looks at this forum. My son has a 2012 insignia with major mot issues around headlamps, o/s is full of condensation and the ballast has blown bulb has blown and the motor is seized, also the ecu's ? are dodgy. The n/s has issues with intermittent failure of the ballast and motor and also needs ecu. Any help with ideas af where to find this stuff, been told ballast is main dealer only and I have no idea where to look for ecu's other than md. Any help will be appreciated, thanks Rob

Hi. My cure for water or condensation:   Vauxhall Insignia 2010

Remove front bumper, and headlight. Clean the top edge of the headlight where dirt collects and rainwater floods over the top allowing seepage between the clear and black seam. Shake the water out via the two drain holes, drill a small vent hole at the lowest point. Fill the upper seam with silicone. Leave to completely dry and refit. Not difficult and for no money. Cheers
