You have to drill into the back of the headlight. Look where the tabs are that hold the reflector in (there's three), and drill holes there. You'll need just enough to get a little screwdriver in there so you can pop those tabs out. Once you get that reflector popped out, you have to break it apart inside the assembly (I used wire cutters), and pull the pieces through the corner bulb hole. After that, you will have fun using a vaccum, maybe a toothbrush, and a lot of patience getting the little pieces left over out. Then seal the holes with silicone. You may have to take your lights off again in a week or so and get some extra pieces that were rattled into view. Have fun. Oh and replace the orange bulb with a clear one for the best-looking setup.
