An HID Conversion Kit will not damage your headlight.
The bulbs will run at 35W, less than the stock ones.
Just be careful if you decide to buy Xenon Bulbs, some run at high wattage and can damage wires, connectors or even headlights in the worse cenario...

the HID system should not melt the housing.
we have been selling HID kits for 2 years and we already saw wires and connectors damaged by high wattage bulbs (not HID bulbs)...even a little damage to headlights - high wattage bulbs exploded inside....but we never saw a melted housing caused by an HID system.
I had crystal clear headlights with 55w H4 super white bulbs and after a few nights they melted my housings. I got a new set of crystal clear headlights and put in a HID setup and have not melted anything for a year. The HID bulbs are brighter and use only 35 watts and therefore burn cooler. I compared the H4 and the HID bulbs side by side and you can feel the difference in heat output by the H4. The H4 is much hotter.
