You should be able to figure out how to take your headlights out of your car just be gentle as you don't need to apply much force. There is no need to remove the front bar, just a few retaining screws and plugs, very easy.

To take your headlights apart, remove any screws that may be holding the lens onto the housing, from memory there are at least 6 with one hidden behind some sticky foam (I have a B4). Put these in a safe place for re-installation later. Dont' worry about removing the rubber seal around the top edge. I also removed all the other bits like the plugs and bulbs as you need to place the headlights in the oven. Not sure if everyting needs to be removed I did just in case.

As I said you need to bake them in the oven. This will loosen the glue between the front clear lens and the rear of the housing. Pre-heat the oven to about 120-130 degrees celsius and place one headlight on on a tray with baking paper for 6 minutes. Dont place it too close to the heat source

Take the headlight out of the oven (using some oven mitts or gloves). Use a couple of flat blade tools like screwdrivers to pry apart the headlights. Stick one screwdriver in between the lens and the back of the housing and pry it apart. It won't come off in one go so just work your way around the headlight. If you work too slow the adhesive will harden, in this case just place the headlight back into the oven and start again. You might need to adjust the time you leave it in the oven depending how warm the housing still is. Don't get any adhasive on your reflector or lens and becarefull not to scratch anything.

I'm sure you can work the rest out. Just repeat the whole process in reverse order once you are ready to seal up the headlights.

Just as a suggestion I would take a closer inspection of your headlight housing and make sure everything is sealed up. I can't remember my headlight suffering from foggyness.

there is a polish that gets it out but only for a limited time....my advice would be look for a secondhand headlight....cheaper in the long run. as if you pull it right apart, when it comes to sealing it up it will no seal and you wil get moisture in the headlight etc, which will cause more headaches as the bulbs will burn out and other things will corode due to the moistuer being there...

It they were my lights, I would pull the headlight from the car then inspect them to try to figure out why there was moisture building up in the headlights in the first place then go from there. It may be a loose fixture or some unexpected hole etc. Taking the headlights out of the car is really easy and only takes a few minutes. However pulling the lens apart from the housing is royal pain in the a*s.

If your deadset in pulling it apart, remember to reheat the headlamp in the oven when it comes time to reseal and use as many clamps as you can fit on the headlamp. Alot of projector retrofitters don't worry about the silicone, they just reheat and reuse the existing adhesive, however it dosen't hurt to use some 100% rubber silicone.

Are both headlamps foggy or is it only one? Are there actual moisture droplets or is it hazzy blured rough up plastic?

RX25SE - When you say "sometimes the polycarbonate lenses go 'foggy' when exposed to ultraviolet light (wrong headlamp globes)" does this mean the lens becomes foggy on the inner side (reflector side) of the lens? I have heard that the protective layer on the outside can be damaged via cleaning etc and become hazzy but I haven't heard about it getting damaged from the inside.

well iv tried to remove the lights from the housing by heating it up etc, but i culdnt get it to come apart... one is alot cloudier than the other. culd it just be from light exposure wear n tear nd its jus tarnished the covering....

ahk, wat kind of plastic cleaner did u use peal? i washed the lights and the fog disappeared but then it came back when i dried it. so i know its not on the inside. i then used mineral terps nd it has kinda worked but still not really clear.

oh ok. cheers for the help ill try it this weekend.
