Fog Light Install help-C300 4Matic 2009

So I'm installing an H7 HIDs for the fog lights and my friend is having difficulty. I ordered an E39 adapter that someone else claimed should work. Is it possible that would melt the housing? Or is their another adapter or bulb that could fit the fog lamp. I have a C300 '09 4 matic with the sport and xenon package. Been dealing with these problems a month now. Any tips?

You won't melt your housing unless you have 55W kit. 35W kit should be safe in your fogs. The E39 plastic adapter still requires a little bit of trimming.

and remember after installing hid for fog you will have to turn them on manually or your cornering light will kick in, or if you know someone with star they can completely disable the cornering light feature.

He won't melt them even with a 100W HID kit. The fog lights are metal and glass. If he's concerned with the adapter, that won't melt either since there is no direct transfer of heat to it.

I thought the reflector part of the fog housing was actually coated plastic material and not metal (I'll have to take mine apart to take a closer look to confirm that). As are the connectors.

The reflector bowl is cast aluminum. I bought a brand new set a few weeks ago and it still had some of the powder/sand from the mold caked into the crevices. After I chipped the powder away there was bare aluminum. The exterior of the bowl is then coated in glass enamel - the shiny brown stuff - to prevent corrosion, and then the interior is mirrored using most likely the AVD (aluminum vapor deposition) technique.

The bulb seat/adapter is still plastic but I'm guessing it's talc filled polypropylene which would make it have a higher thermal tolerance. Typically talc filled plastic is used near sources of heat or lighting units.
