Problems associated with White H7 Xenon HID Light Bulbs

I recently purchased a set of two White H7 Xenon HID Light Bulbs to replace the light bulbs that came with my 2004 treg. I didn't know how to install them myself and the Volkswagen dealership said they would do it for $30. When I took them in the mechanic said that they might melt the light housing and then I would have to replace the whole headlight unit!!!! The specs for the light bulb are Hyper White, 5000K Color Temperature and the Type/Volt/Watt:H7, 12V, 100W. Before I go installing them and possible damaging my vehicle, I was wondering if anyone else had installed bulbs such as these and had any problem with melting the housing or frying the electronic due to the hight wattage and voltage (both are double what the factory bulbs are).

Just say, "NO!" .

Nothing good will come of playing "Dr. Frankenstein".

You can get an H7 bulb with Xenon gas in it, that will burn in the standard lamp holder, at standard wattage and voltage, but provide a whiter light at around 4000K - Philips and Osram both legally offer this in the USA. They are referred to as Ultravision bulbs or words to this effect. The standard for H7 halogen is 3300K, which is noticeably yellow-ish. There is also an advanced H7 that throws a longer field, that would mimic the reach out of HID. But trying to make a halogen Touareg into an HID truck is not a good idea. No reputable manufacturer will offer any path for this - you'll only get the unknown players offering what is at best a gray area changeover.

Call me if you want more color on this?
